(ITS#3932) regex/librewrite concurrency issue

There may be concurrent accesses to regex_t datum by librewrite; if regexec is
not thread safe (which I suppose is not) this may result in concurrency issues.
I randomly experienced this with test039 on a 4 CPU machine; never experienced
it on single CPU machine.
