in thread Forking and running all child processes at the same time
As pointed out by BrowserUK in this node Re: Unix Review column, your:
won't work on windows systems. The windows implementation uses the negative of the thread ID as the pid, so wait returns negative numbers for all children.
It seems the most cross-platform wait statement is:
1 while wait > 0; # avoid zombies
since the main thread is ID 1, and the child threads won't have that ID. And it's what wait natively returns when there are no further child processes.
1 while wait != -1 ; # avoid zombies
