I was unable to reproduce that using the following command:

	echo posix_getppid() . "\n";

TextMate sets TM_PID so you can use $_ENV['TM_PID']. Granted, we did 
this only for the interactive input support which no longer exist, but I 
see a few other things now rely on it, so should probably not remove it.

There is also TM_PROJECT_UUID and TM_DOCUMENT_UUID, which are meant as 
“public API”, but those are per-project and per-document, so 
they’ll live shorter than the session (but figured the info might be 
useful in this context).
