Tried that and got an unexpected result, after some single-stepping in
the debugger it jumped back to the shell prompt on the console and the
Tcl test, running in an xterm window, woke up, threw an error for the
test that had stuck, and continued on to the end of the run. The error
message is included below. I've got a couple of hundred lines of single
step debugger output as well if anyone wants to have a look at it.
