Jan,
You
shouldn't run anything time-consuming in the post-commit hook. And
certainly nothing that generally can't run multiple times concurrently
(such as builds).
What
I would probably do in your case is implement a continuous integration
tool, and use it to detect and execute these post actions on a commit.
That way, if there is a flurry of activity, the
setup will handle the post work
elegantly and correctly. I would do this at the very least for your builds.
Quicker things (commit emails) are perfectly appropriate for post-commit.

Hope this helps,
Rob
