The context is opening things like /dev/tty.  Right?

I had similar problems ages ago.  I don't remember the exact context.

My solution was to use O_NONBLOCK to open the tty, then turn on CLOCAL, then 
close and reopen without O_NONBLOCK.

That may be a wild goose chase, YMMV, etc.  That was on Linux.  I don't know 
how portable it is.
