I suspect the question was rather more specific than that, due to
bad experiences with LinuxThreads.  Does FreeBSD have a proper
signal delivery model, where thread masks are per-signal, and signals
sent to the process when all threads within the process have the
signal blocked remain pending against the process so any thread may
accept the signal using sigwait()/sigtimedwait()/sigwaintinfo().

I suspect the answer is yes, but I haven't played with threads on
recent versions enough.
