I batch tested both versions - the one with "require" and the one with
"use" - 1000 times each (just to be sure, I did not miss any race
conditions). The result is: The code with "require" works 100%, the code
with "use" never works - even though the module is loaded at the very
beginning and not in every thread separately. This cannot be a coincidence.

It was probably a coincidence that your code worked. Loading
non-thread-safe modules should be done separately in the child threads
and main thread (after launching the child threads) so that neither
copy interferes with the other.
