By God, you've hit the nail on the head. Both calling _exit() and
setting LD_PRELOAD to the library list methods work. However, there are
still disadvantages. Calling _exit() will not flush and close open
streams, and while PHP certainly shouldn't have any open streams by the
time it calls exit(), it's still a consideration. As for the LD_PRELOAD,
will it work on all systems? Even if it does, that's requiring user to
set something in their environment just to run a program, which is not
very nice.

Are there any other solutions? How do other bindings do it? Python is
obviously not linked with libgtk..
