I changed `test/runtests.jl` to collect `@testset` results from files and generate a nice report at the end, also using `@timed` for more statistics (gc time!) instead of `@elapsed`. But we have some problems:\r\n\r\n- [ ] not sure how to work with `parallel{_exec}.jl` and `boundscheck{_exec}.jl` - need to pass testset results along from the `exec` files.\r\n- [x] `test/test.jl` is broken because of changes I made!\r\n- [x] Make printing more attractive - somewhat done, now sending error and failure info to `STDERR` which it seems to me we should have been doing all along. Need to print error backtraces still. Should we align the gc time/memory info I have?\r\n- [x] Tests may be much slower now\r\n- [ ] Make **sure** that packages can use this as a drop-in no-effort replacement\r\n- [x] print the error backtraces right\r\n- [x] return `max_rss` as part of the tuple in `runtests`\r\n- [x] the build needs to not time out/segfault\r\n\r\nI would really appreciate help with any/all of this. cc:
