I've tried putting my system at 100% with some bat files

----------
@echo off
:loop
goto loop


And putting them in realtime. I've experienced a crash if you hit 
Control+Z (pause) when you see "waiting" and the 'fg'

machine AT VAIO ~/temp
$ time ./a.exe
running "sh -c 'sleep 1; kill -2 5856' &"
waiting
unblocking

real    0m2.231s
user    0m0.015s
sys     0m0.092s

machine AT VAIO ~/temp
$ time ./a.exe
running "sh -c 'sleep 1; kill -2 11832' &"
waiting

real    0m0.890s
