Notes about methodical extinction
Basic idea: stay at the top of the dungeon while patiently and systematically wiping out all the species, then stroll through the uninhabited Mazes of Menace with your massive amount of gear.
Use level drain ("drain life" spell directed at yourself, or toss Stormbringer up in the air) to maintain control over which monsters appear at a time.
When you cast "create monster" after all monsters of appropriate difficulty are extinct, there is no message but nothing happens. If you cast the spell and you don't see anything appear, check to make sure you didn't get a mimic (sometimes they appear on top of an adjacent object, pretending to be that object) or a centipede or similar hiding under something. Then increase the difficulty by raising your experience level. How to raise your level: blessed Restore Ability brings you back to whatever you drained yourself from. Uncursed or blessed Gain Level obviously also works. Wraith corpses.
Best to have an altar. Sacrifice religiously and pray every time you get a feeling of reconciliation - this turns the altar into a highly productive spellbook factory, and occasionally lowers your AC. If you've been using level drain, it also sometimes restores a level, so be ready to re-drain yourself. Altars are also the best way to clear up troll corpses when you get to the point that trolls appear.
If you are chaotic, sacrifice all the corpses of your own race. Let the peaceful foocubi wander around on your level. Do whatever you want with the other demons, but having those around lets you recharge your Power pretty easily whenever it runs out.
At low experience levels, you advance pretty quickly just by killing monsters. Go ahead and let yourself get up to where monsters of difficulty 1-4 are showing up all together for the first "tranche" of enemies. If you stay on dungeon level one, that would be XP level 7. There are 59 monster species in that tranche, giving you 7,080 individuals. 
The next tranche is difficulty 5; 18 species for 2,160 individuals. This tranche includes nymphs. Difficulty 6 is 26 species for 3,120 individuals - this includes lizards and unicorns. Save the horns to polypile magic markers. Difficulty 7 is again 26 species for 3,120 individuals - this includes chickatrices. If you don't already have an icebox by this time, consider wishing for one so you can save the footrice corpses. You can also tame the footrices if you want to get all the peaceful coaligned unicorns out from underfoot without accidentally killing a bunch of the peaceful foocubi (any that do get stoned can be restored with the stone-to-flesh spell).
Speaking of killing peacefuls, if you want to keep those foocubi peaceful (makes it a lot easier), avoid letting them see you attack another peaceful thing. One way to do that is to build a little boulder house around your altar.
It can be helpful to dig all the walls out of the entire level and use scrolls and wands to make the whole thing lit.
