I see.. ok, I'll keep waiting patiently...

The memory savings is quite significant, and I'll admit that the 8 extra
machines are smaller than the original 4 so it's not exactly 3 times better
cpu-wise...  the memory caching is where the largest savings comes with disk
IO, we have a very high traffic site--usually 3 terabytes transferred per
day, last few days have been more like 5 terabytes due to a new release.

Not exactly the same thing as bribing a commit, but this could get similar
results:  My manager's manager is actually not opposed to hiring a
contractor to fix this... anyone want a temporary job?  I don't know if this
is the right place to say such things, tell me if there's a better place.
When you've got millions of dollars worth of sales depending on an open
source project, throwing a little at the open source project isn't such a
big deal...  I'd gladly do it myself with my company's blessing (on the
clock, not volunteer) but I'm not a very experienced C programmer yet, more
of a Perl hacker and applications architect so far.  This little paragraph
had better not get me too flooded with resumes or flames or I'm going to
feel dumb, whatever you do don't spam this list with personal replies!   ;o)
