That's a really esoteric thing. Any half recent Linux system will have
it installed?

If not, in long run there will (hopefully) be packages and TBB should
depend on pgrep (if decided to use it).

If Mike wants to fulfill the esoteric requirement to POSIX and coreutils
pre 8.13 compatible, the script could test if pgrep exists and leave
them with the current behavior.

I fail to see the problem? Please elaborate. Tor Browser should also be
compatible with system wide installed Tor/Vidalia. (i.e. apt-get install
tor vidalia)

What's the suggested solution here? Why not write those data into a file
or environment variable?
