OK, so looking over this list, it looks like all the major BSDs are 
represented to varying degrees (even the Bitrig guys have a cluster 
running on Bitrig).

According to that site, it looks closer to a biculture of Linux and 
Windows, but I admit that this could be deceiving, and it's really a 
monoculture of Linux.

This should be relatively easy to diagnose, and quite possible that some 
of the information on that FAQ is outdated (i.e. is Tor on 
OpenBSD/NetBSD/Solaris still forking processes instead of using threads? 
Again, should be relatively easy to at least diagnose).

I don't have the spare hardware to test this myself atm (nor do I have an 
ISP nice enough to let me run a Tor relay) but if someone out there is 
running Tor on OpenBSD, I'd be interested in your outlook on this.
