How best to write this if-else?...threads

[Harry George]

Yes, perl itself is in trouble when "match" meets threads.  That is
why my pyperl module allows a separate PyPerl object instantiation for
each thread -- so the PREMATCH et al. are protected.  Globals are not
used.

I don't see why re can't similarly provide a thread-safe unit for the
"globals".
