Subject: Given that POSIX already has AutoLoader loaded, move as much as
X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?a=commitdiff_plain;h=983cc415f583bfaa52651cd66170082fc1c95039;p=p5sagit%2Fp5-mst-13.2.git

Given that POSIX already has AutoLoader loaded, move as much as
possible of POSIX::SigRt out to AutoLoadLand, so that it won't be
loaded unless someone starts using the realtime signals interface.
