Description:
------------
I am running PHPT tests on an SMB file share (and also sometimes DFS) served by a remote file server. The share is mounted to a local drive (H:) on Windows. This issue occurs on Windows 7, Vista, 2008, 2008r2, 8, 2012, x64 and x86 (I am using the PHP on Windows binary build from windows.php.net without any modification).

When I run these 2 PHAR tests, sometimes, they crash:
ext/phar/tests/zip/phar_commitwrite.phpt
ext/phar/tests/tar/phar_setsignaturealgo2.phpt

See attached BTs.

If I add additional traffic to the network or file server (ex: download a big file on another computer), the crashes happen more frequently. Even then, I'm only adding max ~10MiB/S to network or file server which isn't really heavy load.

The file access times on the share are still pretty normal (fraction of a second max, to read a PHPT file, so the network or file server is never heavily loaded).

I believe this is a time issue that is load induced.


Actual result:

About NAS, it may be possible.

For example,
My company's NAS Buffalo Ls-L series freezes sometimes when I try simultaneous client accesses.
It seems that NAS exhausts its ram memory by operating multiple file requests.

Crashes should be fixed by now (testing) but the reason why tmp files creations 
fail has to be analyzed and fixed as well. Assigned to me.

I think I found all locations causing these crashes. Matt, let me know once the 
last serie of tests pass (stress and compat) so we can close it :)

I haven't seen this bug repro on any recent 5.3, 5.4, or 5.5 snapshot builds.

I think this bug is fixed.


I have added a documentation note about the importance of setting the `sys_temp_dir` directive, especially when using remote file systems: http://us3.php.net/manual/en/book.phar.php
