Bash-4.2 will sleep for 1, 2, 4, then 8 seconds if a fork fails, trying
after each sleep to reap dead children.  It will give up after that and
report the fork failure.  You'll see messages like this:

$ ls
bash: fork: retry: No child processes
bash: fork: retry: No child processes
bash: fork: retry: No child processes
bash: fork: retry: No child processes
bash: fork: Resource temporarily unavailable
