I dont even know what threads are but mysql on 3.2-release doesnt work with -lc_r unless you get a different one, like from 3.1 or -current. otherwise you have to use mit-threads. I am on a mysql mailing list where the majority of freebsd questions involve problems resulting from having to use the mit-threads included with mysql instead of -lc_r. I lost a decision between freebsd & linux being used for a client because of this. I must say though, that on my -current box -lc_r has worked alot of the time in the last few months.
