Symbolic WCHAN for 4.[12] ps.

[Guy Harris]

Speaking of control-T implementations, every one I can think of on UNIX
actually sticks a mini-ps in the kernel which is called from the TTY driver.  If
I remember correctly, the original TENEX ^T sent a signal (or its TENEX
equivalent) to either the entire process tree or to the top-level exec,
which woke up and did the "ps".  Just out of curiosity, has anyone implemented
a UNIX ^T as just another interrupt character and hacked a shell to catch
it and do a "ps"?
