in reply to Is fork() supported in win98?

While we are talking about efficiency, fork() is really not the speed efficient way under Win32, as fork() is not a native OS feature. fork()ing under Win32 currently means that the whole process space is copied, at least all data has to be copied into the forked child.

Personally, I found besides the performance issues also some weird behaviour with sockets when using fork(), but that may have been due to using Windows 98, strange Perl code or the phase of the moon.
