Has anyone seen this weird behavior from Mac OS X's SMB client?

[David Collier-Brown]

On Solarii, the first kind of botch tends to get smoothed out someplace
downstream of the strategy routine in the driver, during coalescence.
Alas, this is at the cost of a whole wodge of system calls doing short
I/Os from memory.  They would better be handled way upstream, perhaps in
a vfs that could itself do coalescing.

The second I'm less sure about: I *think* the same thing applies,
assuming I'm interpreting it correctly...
