chroot
About deleting a directory after doing a readdir/closedir on it... I'm not sure if this is the solution, but you could try to chdir("/"); before the rmdir to make absolutely sure you aren't standing in the directory (i.e trying to pull out the rug from under yourself).

The manual says that one should only call closedir with a parameter which is an open directory handle.
The manual usually lists warnings and errors generated by violating a "should" or "shouldn't", but doesn't for this case.
In fact, one gets the runtime error
Warning: closedir(): supplied argument is not a valid Directory resource in whatever.php on line nn
irrespective of whether it's an already-closed directory handle or whether it's total junk.
[Different error messages would have spared me a little debugging. Sigh. It would be nice if the manual said.]
