Subject: Add a threads stress test for regular expressions
X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?a=commitdiff_plain;h=31623e47b5a5de87609f69bb07d5757a8d12702f;p=p5sagit%2Fp5-mst-13.2.git

Add a threads stress test for regular expressions
(mostly just a modified stress_string.t) and doesn't
test that much of regular expressions, just that $1
doesn't get stomped by competing threads (as it does
in the 5005threads of old).
