Normally, XS code gets calls from pp_entersub, which is in a runops loop,
which is either at the top-level or has been invoked from something like
call_sv(). In those circumstances the XS code would be automatically
'wrapped' and old-style XS code would run just fine.

Your XS code getting called from the keyword plugin interface is an
unusual route and thus is somehow not getting wrapped, and most likely
implies that I need to look into it and ensure that that route gets
handled correctly by the perl core too.

I'll add it to my list of things to look into.
