Where do the filehandle structures live in the latter case?
The place you clearly think so little of that you need to ask:
process-global (or process-local depending on how you think about
it) storage. And everything in that storage must have locking.
You'll have to look at specific implementations. One that I can think
of off the top of my head is Perl 5's "ithreads"; there is a
distinguished allocation store which is global to all ithreads, and
the interpreter instance gives you primitives for locking and mutexing
(see "use threads::shared;").
