/*
* a subprocess will initially inherit the process group of its parent. the
* process group may have a control terminal associated with it, which would
* be the first tty device opened by the group leader. typically the group
* leader is your shell and the control terminal is your login device. a
* subset of signals triggered on the control terminal are sent to all members
* of the process group, in large part to facilitate sane and consistent
* cleanup (ex: control terminal was closed).
*
* so why the overly descriptive lecture style comment?
* 1. SIGINT and SIGQUIT are among the signals with this behavior
* 2. a number of applications gank the above for their own use
* 3. ruby's insanely useful "guard" is one of these applications
* 4. despite having some level of understanding of POSIX signals and a few
* of the scenarios that might cause problems, i learned this one only
* after reading ruby 1.9's process.c
* 5. if left completely undocumented, even slightly obscure bugfixes
* may be removed as cruft by a future maintainer
*
* hindsight is 20/20 addition: if you're single-threaded and blocking on IO
* with a subprocess, then handlers for deferrable signals might not get run
* when you expect them to. In the case of Ruby 1.8, that means making use of
* IO::select, which will preserve correct signal handling behavior.
