I don't know if this helps, but you could gut the code below to get the sort
of effect you want.
This code is my wrapper for an application.
The payload -- the main application is the line Do %esinMain.r.
The rest of the code simply wraps this in a Try block. If an error occurs the
error recovery does one of two things:
-- If the error is a specific user error it automatically restarts. The
application triggers this error to force the sort of restart you want --
somewhere in the depths of the application this line triggers a restart:
make error! "restart-request"
--Any other error is logged and reported, and the user offered the chance to
restart or quit.
(Watch out for strings wrapping across lines in the cut'n'pasted code)
