So don't drag the window borders; use d.resize. Or configure your
window manager not to continuously emit resize requests during
dragging.

It may be possible, but it would be a great deal of work, and pretty
easy to get wrong.

The monitor has to spawn a child process to do run the commands, as
the main process has to keep running to service the requests which the
commands generate. The child process doesn't have anything to do with
X, and changing that (i.e. having both processes read the same X
connection) would be complex.
