Improve performance by using a hash table or a faster approach
for looking up ids. Currently an automatic "move-to-front-when-accessed"
mechanism is implemented.

Output more information in /proc/fusion.

Improve performance (especially message throughput) by avoiding kmalloc.

Implement defering/blocking of SIGSTOP while a Skirmish is locked
by the process. This will avoid rare deadlocks when pressing Ctrl-Z
in the terminal where a DirectFB slave application has been started.

Maybe implement other Fusion parts like Arena or Object(Pool).


Replace kmalloc() usage.

Revert semaphores to spinlocks.
