2.2.0: Memory fragmentation!?

Hello list,

since 2.2.0-final (aka pre9) memory fragmentation seems to be an issue
again. I've never seen that happen before on my box at home, but since
pre9 I experienced one lockup that seemed to be because of failing
kmallocs, and very often sound failures because of the kernel beeing
unable to allocate a contiguous block of 64k..

I've often read about memory fragmentation beeing a problem, but I've
never experienced it myself. Seems that pre9 brought a change in the
memory management that leads to a higher degree of fragmentation, but
this is only a guess.

My machine is a PPro with 64Megs of RAM, it's a desktop system and thus
only moderately loaded..

Gruss,
Matthias
