Is there any way to prevent a SIGINT signal from propagating to a
background child Windows process?
I'm trying to write a script to start a Java application server. I want
the script to trap Ctrl-C and send the app server a command to shutdown
cleanly, but it appears the Ctrl-C is immediately propagated to the Java
process, even though the script traps it.

Signal handling interoperability is lacking more generally.
Even SIGTSTP is propagated in such a way that the Windows application is
terminated.
(Try running notepad from bash, then type Ctrl-Z.)
