This is a question about frozen frontend behavior.
In development stages, one of my frequent mistakes is to send the
frontend something that takes forever to dynamically update---at least
that is what I believe what is happening for most of the "freezing"
occurrences. For MacOs, this is often signaled by a "Formatting
Notebook Contents" window.
I wonder if anyone has found a method to send the front end a message to
stop dynamically updating while in an unresponsive state? I've various
versions of kill -s signal (i.e., signal = INT) from a terminal in
MacOSx, but never with success.
I suppose that having the front end query the operating system for
interrupt requests would create a lot of overhead. However, I wonder if
a method to force the frontend to make an operating system query with a
user-specified time interval might be possible?
