I'd like to talk to someone about a bizarre problem I am 
encountering in writing a Unix socket driver. 

In a *very* brief nutshell, I am experiencing behavior which 
seems to imply that Unix is blocking all IO interrupts *except*
when screen I/O is going on via printf. 

I know, I know...it doesn't m,ake sense to me either. Anyone
out there willing to listen to my tale of woe?

My environment is a Sun 4 runing OS 4.1.1, but I get
identical results on a Sun 3 running OS 3.x.x

Thanks in advance....
