[pcre-dev] Revision 922

I just saw the change in the commit log:
> Set PCRE_EXTRA_USED_JIT when JIT was actually used at runtime

So here's the stupid question of the day: doesn't that break
thread-safety? Now using the same pcre_extra block in multiple threads
causes races on who sets/clears that flag.

Cheers,
