Something like that almost works, in fact, vim has a c program
that does something like that, to compile & run in the background.
The reason I wanted 'screen' to do it is that screen is already
running, I didn't want to create a whole process just for blinking
the silly cursor. (It's not worth a whole process)
I looked at the screen source for the event loop, trying to
figure out where a person would insert a couple printf statements,
but to no avail (with it's socket handling etc.. probably best
to leave well enough alone, I couldn't very well install the patch
on every screen utility on every host for a blinking cursor anyway.
:-) )
