Hi,

I'm trying to find the most processor-efficient way of writing some code to do the following:

someLoop {
  ...
  ... do stuff ...
  ...
  if(I *don't* have one and only one child proc running) {
    launch asynchronous child process
  }
  ...
  ... carry on doing stuff while child runs ...
  ...
}

I've played around a bit with fork(), but:

(a) Do not know whether it is the most efficient and stable way of doing this.
(b) Do not have enough Perl experience to be able to ensure I only ever have JUST ONE child running at any time. I only seem to be able to fork multiple processes.

Any advice, particularly code examples, would be appreciated...especially for how I can do the check in the if statement.

Thanks,
Roadrunner.
