linux-2.6.17/Documentation/feature-removal-schedule.txt says:

What: mount/umount uevents
When: February 2007
Why: These events are not correct, and do not properly let userspace know when a file system has been mounted or unmounted. Userspace should poll the /proc/mounts file instead to detect this properly.

Also, try and detect if an unrelated process is running without polling (hint: *notify doesn't work on procfs).
