but at the same time, threads impose a rather substantial overhead penalty as well because they force Perl to implement preemptive multitasking within a single process, which is no mean feat.

Not so. All the preemption and multitasking is done by entirely by the operating system, regardless of which OS it is running on. Perl uses either POSIX threads or Win32 native threads.

Unlike Java and several other langauges which do implement their own mini-schedulers within each process, Perl leaves all the scheduling to the OS.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
Lingua non convalesco, consenesco et abolesco. -- Rule 1 has a caveat! -- Who broke the cabal?
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
