What operating system are you running?  If it is 4.X BSD I know what the
problem is but haven't got around to fixing it.  The problem is in 4.X BSD's
signal mechanism.  The hangup routine sets a flag which is tested on return
from the input command read.  The read expects that it will be aborted
when it is interrupted, which, of course, doesn't happen in the Berkeley Unix
dialects.  A cure is to replace the synchronous signal routine with a
longjmp construction.
