Reserving the slots not per se. But allocating 10000 semaphores, mailboxes or 
tasks might give you a different experience. The amount of primitives you can 
create without crashing varies over RTAI versions too.

But 100 is inconveniently low indeed, I run my system at a 1000 for small 
programs. Another trick that you may pull is disabling the slot registration 
alltogether in the rtai core code, but this requires hacking of RTAI 
internals I'm not familiar with...
