Hi,
I've updated the patch according to your comments.

I added a _dbus_delete_directory () instead of using rmdir directly.
Also found _dbus_sleep_milliseconds so I use that instead of sleep.
Moved in the #include <stdio.h> inside the DBUS_BUILD_TESTS #ifdefs.

doh, thanks :)

I've changed the patch to add a BusServiceDirectory struct that keeps
the directory part of the string together with an hash table of all the
service entries in that directory, the entry now keeps a pointer to such
a directoy along with just the filename part.
Made the implementation nicer aswell :)

I think I've managed to fix them all, ...

Oops indeed, fixed.

The unit tests with oom handling is pretty fast, especially compared to
those for dispatch tests.

Hmmm ;)
