1) Processes hang, usually forever.  This is mainly noticeable
as a DECterm locking up.  It can be in the middle of anything.
Output is pouring onto the screen, then nothing, not even character
echo as I beat the return key in frustration.  Sometimes the process
comes back after a few minutes, but most of the time I end up
quitting the window (I let one go all day, once). I suppose this
could mean it's the DECterm, not the process being run, but other
high i/o system processes seem sometime to pause for several seconds
when nothing else is going on.  This, of course, is a hard thing
to tell; perhaps I'm oversensitive given the situation.  DEC say
there is a scheduler problem with 4.0 and gave me a patch, but it
has done nothing.

2) When rlogged or telnetted to another host, ^S is only let thru
to the remote system intermittently.  I notice this one when using
emacs.  I start up and hit ^S to do an I-search with no problem,
then do it again later and it's being ignored.  This doesn't occur
in windows on the local host and never happened with V3.1 and the
same emacs on the remote host.  DEC has no answer for this one yet,
but are sending me a patch for a different DECterm fix that they
hope might do something.

Thanx to anyone that can provide any information on these problems.
I'll post anything useful that I hear about.

Cheers,
