It is unclear what you mean by "remember global vars"; it is intended
that global vars are remembered across calls to rewriting; note, though,
that after successive rewritings, the old value by design is REPLACED
by the new one, so there should be no leaking. If you found any, that's
a bug, and it is a completely different matter.

I haven't been playing with the rewrite stuff for a while, and there
might well be locking problems out there; however, I suggest you don't
deal with rewrite internals and stay with the published API, that is
functions that live in include/rewrite.h; the function you mention is
in libraries/librewrite/rewrite-int.h and, as such, it is intended
to be used only from inside librewrite.
