[Pharo-project] Problems saving the image on SIGTERM

Jan. 8, 2010

      Hi,

Chaff is a tiny class to intercept the SIGTERM signal and save the
image http://www.squeaksource.com/Chaff.html

Several problems:

- OSProcess accessor forwardSigTern will only work once. Once the VM
has registered a handler for a given signal, it can't clean it up or
register another semaphore, until the image restarts.

- If I have a process waiting on the semaphore, but the image quits
for a different reason, I guess when it restarts, the process will
still be there but the semaphore will be invalidâ¦ what's a good way to
handle that ?

- OSProcess does not seem to be able to register signal handlers at
all on the Cocoa VM (5.2b9)

Cheers,
