[fireball] 42098: - Properly implement add_timeout_user / remove_timeout_user (thus eliminating non paged pool leakage of a test implementation). - Debug prints are still turned on because remove_timeout_user seems to not being called.

Log:
- Properly implement add_timeout_user / remove_timeout_user (thus eliminating non paged
pool leakage of a test implementation).
- Debug prints are still turned on because remove_timeout_user seems to not being called.
