Wait a minute: what do you mean by "terminal-mode buffer" into which
you need to go?  More generally, can you describe a detailed recipe
for reproducing the problem on your system, keystroke by keystroke?

You are investigating the error message saying "Failed select".
Search the *.c files for that text, and you will find only 3 instances
of it.  Put a breakpoint in all these 3 places, then do whatever it
takes to reproduce the problem, and you will be able to collect the
information I asked about.
