use case  logd running as a service  logd reinit is entered on the command line  it is only purpose in life is to send a kill sighup to the one running as a service i could circumvent popen ing out to pidof for the hard coded  system bin logd process if i implemented a private copy in logd  or by making a command call to  dev socket logd control to tell it to reread  better i may just do that instead  i always viewed popen as a security hole
