Appveyor build failure

Hi!

I've noticed quite a lot Appveyor build failures recently.  A particular
problem appears to be ext\fileinfo\tests\cve-2014-3538-nojit.phpt[1],
which is supposed to be finished in one second, but run slightly longer
mostly[2].

Anatol, should we simply increase the allowed time (to, say, 1.5 sec),
or is there an underlying issue which would better be solved instead?
