For example, these tests fail due to a platform difference in their use of the builtin PHP sys_get_temp_dir.  See the comments at:

http://us.php.net/sys_get_temp_dir

"""This function does not always add trailing slash. This behaviour is inconsistent across systems, so you have keep an eye on it."""

When running layout tests on Linux, sys_get_temp_dir does not return a trailing slash.  We can see an example of the failure via strace:

[pid 13932] open("/tmppreflightCacheTimeout.txt", O_WRONLY|O_CREAT|O_TRUNC|O_LARGEFILE, 0666) = -1 EACCES (Permission denied)

The solution is just to always append a trailing slash, on some platforms this might result in /tmp//blah, but that shouldn't be a problem.

Patch to always append / after the temp directory.

I realized I forgot a ChangeLog, if the patch looks ok I'll add one.

Seems like a fine change. But this patch lacks a ChangeLog entry. That makes extra work for the committer. So please submit a new patch with the ChangeLog entry.

Thanks for the review.  I don't have commit access, so it would be great for someone to commit it for me.
