You should try the same code in Mono 3.0.x to see if the bug has been fixed.

You can try out the Parallel Mono packages for Debian, they should work on
Ubuntu: http://inorton.wordpress.com/pmono-parallel-mono-debian-pacakges/
Otherwise, it's pretty easy to build from source. Feel free to ask if you
don't know how to do this :)
