Yes, I know.  I didn't say the method was perfect.  I find it frustrating as
well. :-/

I have no idea either. :(  I can't magically fix them, and if I don't commit
any of this stuff which works on my boxes as far as I can tell, then others
won't test it and we won't make progress.  If a buildworld usually triggers,
then try writing a small C program that beats on a file in /tmp or /var, then
start up 10 copies of it in a script that you run as your
'command_that_makes_my_machine_go_boom' to see if it works. :-P
