Thanks - it doesn't hang anymore, however, when I run it, it spits out
"0", but I think it should say "1".

On another note, signals seem deferred during fgetc(). Is this right?
I have an interactive cmdline program that should react to a Ctrl-C
during user input, but it is postponed until after the user has
entered the command.

(Here's that last program in case you deleted it)
