Our interfacing with ECL got behind the times a little (and perhaps was
never fully with it). Google e.g.
"Making an external signal handler play nice with embedded ECL"
[http://comments.gmane.org/gmane.lisp.ecl.general/8211 to get to this].
There are more places where we could use a face-lift. ECL has really
improved its thread-ready API and we should really be using that (e.g.,
look up return values and other things on a "ecl_process_env()" data
structure).
Anyway, there are some improvements we could make to handling interrupts
and catching other stuff.
