Yes, that can be done.

I'll remove code for the systems I can't test.

Yes, sure. I can do that. However, I'm a little unsure if I should bother
with all of these changes if they're not going to be committed anyway.
I know of at least a few people who have mistakenly used
System.Environment.TickCount and complained it didn't work the
way they expected it to on Mono. That's why I set out to see if I
could fix it in the first place.
