Installing MySQL: unlimit maxproc doesn't work

[Alexander_(_dot_)_Farber_(_at_)_t-online_(_dot_)_de (Alexander Farber)]

Hi,

I've tried to install the mysql server from 
ports on a patched OpenBSD 2.9 computer with 

    make SUBPACKAGE=-server install

but it failed with the message that /bin/sh is 
unable to fork. So I've decided to increase the 
maxproc limit, but it doesn't work (in tcsh):

    pref# whoami
    root
    
    pref# limit
    cputime         unlimited
    filesize        unlimited
    datasize        1048576 kbytes
    stacksize       32768 kbytes
    coredumpsize    unlimited
    memoryuse       481576 kbytes
    descriptors     1024 
    memorylocked    481576 kbytes
    maxproc         532 
    
    pref# unlimit -h maxproc
    
    pref# unlimit maxproc
    
    pref# limit
    cputime         unlimited
    filesize        unlimited
    datasize        1048576 kbytes
    stacksize       32768 kbytes
    coredumpsize    unlimited
    memoryuse       481576 kbytes
    descriptors     1024 
    memorylocked    481576 kbytes
    maxproc         532 

I've looked into my GENERIC.pref (kernel config file, please see
http://home.t-online.de/home/Alexander.Farber/OpenBSD/GENERIC.pref ),
but I don't see anything looking like maxproc there or in the
included file ../../../conf/GENERIC. What should I do?
