Hey,
I was wondering if anyone had taken an interest in pool(9) from NetBSD --
and now in OpenBSD. To explain what it is, I might as well quote a man
page (I know I'd mess it up ;-), a few more comments below it):
DESCRIPTION
These utility routines provide management of pools of fixed-sized
areas of memory. Resource pools set aside an amount of memory for
exclusive use by the resource pool owner. This can be used by
applications to guarantee the availability of a minimum amount of memory
needed to continue operation independent of the memory resources currently
available from the system-wide memory allocator (malloc(9)). The pool manager
can optionally obtain temporary memory by calling the palloc() function
passed to pool_create(), for extra pool items in case the number of
allocations exceeds the nominal number of pool items managed by a pool
resource. This temporary memory will be automatically returned to the
system at a later time.

I realize the state of -current and all that is going on, especially with
trying to get a 5.0 snap done by the end of the year, but I'd be
interested in seeing it in perhaps a later 5.x? Also, in that 5.x, I'd be
interested in seeing it actually being _used_ by certain kernel resources
-- perhaps VFS related things? If one is so inclined, grep for pool (or
it's functions) in the NetBSD and/or OpenBSD sys/kern director to see
where they are using it in there.
Anyway, any interest in this? Sounds kind of nice, but perhaps we already
have a similar system in place that I am missing?
Cheers,
Andrew
