This raises an interesting question.  How come I can use the plain
Fedora Core 6 kernel (and not the real-time CCRMA kernel) to do audio
works on a x86_64 dual core with 4 GB RAM without any problems ?  Is it
because I'm not doing much ?  I mean, I do not record a chamber
orchestra in real time while jiggling the screen with beryl,
compiling OpenOffice and letting goddamned beagle run loose all at the
same time ?  And leaving Konqueror open with one of those pages that
mysteriously drains CPU cycles to make good measure.

Or is it the dual core ?  Or the RAM ?

Or is it because the Fedora team already incorporates real-time
mechanism into their kernels ?

In other words, why wouldn't the standard OpenSuSE kernel be enough ?

Cheers,
Al
