Question 2: For methods 1 and 3, why do i need to synchronize them? If I do not, the script just hangs up usually after only a few seconds.

I can confirm this problem. I believe it to be a bug in Perl. I think it is to do with the implementation of the wait/waitpid emulation on windows which limits the number of concurrent child processes to 64. I'll try to tie that down a bit further tomorrow and raise a perlbug for it if I succeed.

Meanwhile, on the basis of what I've seen of your code, you should probably try MCE for this task.

Anyone got any experience of this phone's predecessor?
