VNCViewer locks

[dgpickett@aol.com]

I have a variety of SolarisB 8 boxes where I run VNC 4.1.1 with no problem,
but now I have a Solaris 10 box with new 1593 MHz CPUs, and when vi sets the
visual bell off on my xterm, vncviewer locks.B  I ran a truss, and saw that
vncviewer got a zero return from read on the socket.B  Since it is just a
different box, I suspect some subtle timing issue.

There is a similar open thread on vncviewer using SSH, which might be the same
problem.

In the past on Solaris, IB have occasionally seen sockets returning zero to a
read() without being at EOF (connection closed or disconnected).B  We wrote a
loop withB poll(0,0,1) to insist on 50 consecutiveB return zero
read()B returnsB across 50 Milliseconds before declaring EOF to avoid this!

Best regards,

David
