Sorry, there is no such race condition in UNIX but there might be in
no need to apologize :) I was simply referring to the infinitely minute
possibility that rm -rf may possibly fail if someone starts doing stuff
in the directory at juuuuust the right moment.
Its only a race condition in the sense that your command may
inexplicably fail, but its not that big of a thing and the chances that
the race would ever win, I mean the timing of it, the kernel smarts, etc
are so slim you;d probably win the lottery several times before it
happens :)
Anyway how rm -rf behaves on various OSs is slightly off topic so back
to the topic:
File::Copy::Recursive at least returns undef on failure so you can try
again if you like and report the error with $!, and its much more
portable than system 'rm', '-rf';
