ipc_shm: Don't truncate SHM files of an active server (#307)
* ipc_shm: Don't truncate SHM files of an active server
I've put in an extra check so that clients don't truncate the
SHM file if the server still exists. Sadly on FreeBSD we can't
get the server PID for the client (unless someone has a patch handy!)
so we still do the truncate when disconnected. As a backstop (and also
to cover the BSD issue) I've added a SIGBUS trap to the server shutdown
so that it doesn't cause a server crash.
