Can you write a version of blockingSockTest that demonstrates this and 
correctly responds with socketSigAlarmRequired?  Unfortunately you'll have to 
test it against R3.14.9 or R3.14.10 — I eviscerated the sigAlarm routines for 
this release since our use of this signal broke the posix timer library 
(which relies on SIG_ALARM) that some external libraries use.  We'll have to 
switch to using a different signal if we're going to bring it back (we 
probably should make the signal number we use configurable).
