With Textmate 1.5 I used the parent process ID from my

I was unable to reproduce that using the following command:
echo posix_getppid() . "\n";
I realize I could query the system and find the
Textmate pid by name,
but there could be more than one instance running. Is there a better
way to get a stable identifier that only changes if the application is
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).
