I'm sorry I was away from the console during last weekend....
Today I booted new kernel with diff3 patch, and did a couple of tests
(massive thumbnail loading and csup). All of them worked as expected
and no Send-Q stack observed, so I believe the problem is fixed by
this patch.
I really appreciate your swift update!
