vfs.ufs.dirhash_maxmem ... how high can I go ?

[Gore Jarold]

Based on the previous discussion, I have decided to up
my dirhash_maxmem and also to start tracking its usage
over time ...

I doubled it, then doubled again, then again ... and
the system even hit the 16 MB ceiling.

So now I have set it to 32 MB and we will see if the
system can max that out.

In the meantime, are there any unexpected consequences
of upping this value to 32 MB ?

I have 4 GB of physical and 4 GB of swap, running on
normal 32-bit x86, and I have this set as well:

kern.maxdsiz="2572000000"

any comments ?

Also, now that we see that my dirhash usage is _very
high_, any revised comments on the ability of these
workloads to crash a machine that was at the 2 MB
default ?
