i think that it could be fixed with WaitForSingleObject, making it wait
a bit of time to the timeout thread end.

the problem is at zend_execute_API.c
the access violation happens when it free the library before
timeout_thread_proc() finish,
at zend_shutdown_timeout_thread()
after PostThreadMessage it should wait some time to the
timeout_thread_proc() finish.
if it dont wait, the timeout_thread_proc() will walk in NULL bytes
because the code was released by the IIS

We are aware of PHP's problems with stability under IIS and are working
to rectify the problem. Unfortunatly your bug report does not contain
any
extra useful information and we already have enough bug reports open
about
this issue. If you can provide more detailed information such as a
reproducable crash or a backtrace please do so and reopen this bug.
Otherwise please keep trying new releases as we are working to resolve
the problems on this platform

Description:
------------
while recycling iis6 worker process when an user is uploading a file,
php crash with access violation "zend timeout window: w3wp - read error
at address 0x019052a5"
Reproduce code:
---------------
at php.ini
post_max_size = 1032M
upload_max_filesize = 1024M
while an user is uploading a file (post, upload form) (use a big file,
so it wont end before we finish), open iis mmc, go to application
pools, select the php pool (DefaultAppPool if you didnt change it),
right click on it and recycle
im using Windows 2003, IIS6, php 4.4.1 isapi
Expected result:
----------------
it should recycle without crash
Actual result:
--------------
php crash with access violation
"zend timeout window: w3wp"
"read error at address 0x019052a5"
------------------------------------------------------------------------
