That is related to my original hash patch a few years ago. It is not a typo!
If you don't have a special distribution with clusters it doesn't matter if
the hash size is prime or not. In fact the modulo operation is slower
than the AND on old CPUs...

Seems that work needs to be done always twice :( I made similar improvements
for the Reel-vdr almost two years ago (replacing SetIndex by a faster
version without dirty-update). AFAIK RMM also submitted the patches. At that
time nobody was interested in them ("vdr is fast enough" or the like).
