vmstat 'b' (disk busy?) field keeps climbing ...

On Fri, Jun 23, 2006 at 07:12:54PM -0300 I heard the voice of
Marc G. Fournier, and lo! it spake thus:

>     15954 vnode pager pageouts
>    219494 vnode pager pages paged out

This may be something to look at.  My workstation (~3.5 day uptime)
has a fraction of that:

     7204 vnode pager pageins
    37609 vnode pager pages paged in
        1 vnode pager pageouts
        1 vnode pager pages paged out

Compare to the number of processes spawned (I'm at 10x yours):

>     28399  fork() calls
>      1708 vfork() calls
>         0 rfork() calls

   282510  fork() calls
    22164 vfork() calls
        0 rfork() calls


That sounds like hefty memory pressure.
