I doubt many people use it in production, especially under "high" load.
About a year ago I've spent quite some time fixing threading issues in
different parts of PHP (object instantiation in the engine, mysqli, ...)
there were a few bug reports but considering how simple it was to
exploit some of the bugs (<?php new stdclass; ?>, or any other internal
class, was all that was needed for one of the bugs) there were way too
few reports.
