Hello,

I come across the tweak of 'shmmax' and I'm here asking what 
it is exactly the meaning for 'shared memory' here, and if implying
that it is eventually the max memory allocable to the graphic card is
correct. 

>From man sysctl:

     To set the amount of shared memory available in the system and the
     maximum number of shared memory segments:

           # sysctl kern.shminfo.shmmax=33554432
           # sysctl kern.shminfo.shmseg=32

I miss also to understand what is the relationship between shmmax and
shmseg, eg. I actually set shmmax = 524288 dreaming a the *fastest car*.

Thxs!
