Description:
------------
Running multiple PHPT tests on CLI I occassionally get these crashes (see below).
I do this using PFTT, which for this is equivalent to run-test.php except that it runs multiple php
processes at a time, instead of just one.
This is an updated copy of this issue: https://github.com/zendtech/ZendOptimizerPlus/issues/59
Expected result:
----------------
PHPT tests pass
Actual result:
