I had a very similar problem--one turnkey board assembly house would send
us boards, and we had a heck of a time with oscillator startup.  Probably
10% failure, if not more.  I was pulling my hair out over it (as anyone on
the list back then will remember), and of course, the assembly house would
tell me over and over that the flux (no clean) didn't matter.  They don't
build our boards anymore, we avoid no clean flux, and life is _much_ better.

From now on, I'll probably roll my own 4.something MHz oscillator and
divide down to ~32 kHz (or maybe 38.4 KHz--it works out nicely for a 100 Hz
ticker and common baud rates), rather than deal with the fragile, picky,
slow starting 32 kHz rocks.  It's not like the '332 is micropower to begin
with, so to me the 32kHz rock doesn't make much sense.
