I've checked further, and found that FreeBSD correctly handles blocking
signals on a per-thread basis. _But_, all threads still get EINTR when a
signal happens while they're in a blocking read.
I've attached the updated program that shows the correct delivery of the
signals, with system calls still being interrupted. [Sorry about the
attachment, but that seems the safest way to go about getting the file
delivered in usable fashion.]
