Thanks for the bug report. This is actually a problem with the
dialup mint-square, so I'm forwarding your bug report to bug-dialup.
I'll reply to your postscript questions in a moment.
Bug-dialup: mint-square is currently in a state where a process
that attempts to read() the file /mit/sipb/bin/pine will hang
indefinitely. As a consequence, it is impossible for users to
execute /mit/sipb/bin/pine. It would be nice if this were fixed.
As an example, trying to run "wc" on /mit/sipb/bin/pine hangs
forever. Truss output shows that wc is failing to read() the
file. (The time is now 10:10. The process that I started at
09:20 is still hung. The user submitted a bug report to bug-sipb
at 02:20.)
% truss -o mint-square.truss wc /mit/sipb/bin/pine
[hangs forever]
[from a different shell]
% ls -l mint-square.truss
-rw-r--r-- 1 jmorzins mit 1692 Apr 3 09:19 mint-square.truss
% tail -4 mint-square.truss

[comparing this to a wc process that works:]

I believe that I have reported this type of bug at least once in
the past.
