Start a process from within a signal handler

[Jörg Sommer <joerg@xxxxxxxxxxxx>]

Hi,

can I start a new process while I'm in a signal handler?

If latex exits and it requests a rerun I would like to setup a new
process running latex again. But I get the notice latex has quit within a
signal handler where I can't setup a new process. How can I handle this?

Traceback: open_process
***string***:1:<top-level>:Run-Time Error
Traceback: called from eval: open_process("/bin/echo", "halle", 1)
Traceback: eval

	String_Type dir = "/tmp"
