netmcore: becoming a worker after fork+exec ?

Hello ocamlnet developers,

Is it possible to establish the master/worker relationship with a process that has been fork+exec'ed (or Netsys_posix.spawn'ed) but is of the same executable as the process doing Netmcore.startup ?

Let me explain. There is a problem on OSX in that forked child processes cannot access some OS functionality (for example SDL will not work on a forked child process). One has to exec in order to get this functionality back. I would like to be able to communicate with this process (of the same executable if need be) using the convenient netmcore modules but I don't see a way for this process to get a handle on resources managed by the master process. It seems like it is easy to get as far as the getting a handle to the shared memory from which a Netmcore_mempool is created (by simply passing its name as a command argument to exec), but one cannot actually create the resource suitable for interacting with the master and other workers, as far as I can tell.

Any info about this would be greatly appreciated.

Best,
Piotr (Peter) Mardziel <[email protected]>
