So is this actually a bug in Strawberry and Active State Perl, or is Cygwin just applying some magic here to make this work?

Both AS Perl and Strawberry Perl use the MS C-runtime, which is where the internal locking is done. It's not an error, it's a design choice.

Cygwin on the other hand implements a strictly POSIX-complient C-runtime which makes other choices.

In the absence of evidence, opinion is indistinguishable from prejudice.
