Manoj, you said that the number of threads is fixed, with a variable
number of processes?  Why would I be seeing the above?  I'm assuming those
processes with just a few threads showing up correspond to these lines in
the scoreboard:

77.3 requests/sec - 0.7 MB/second - 8.7 kB/request
900 connections currently being processed, 68 idle servers 

.K...K......W....L..W.....W.K....K..........W...K....K.........W
.......K.W......................................................
..W.W.W.....W.....W....W......................................K.

If I understand what you're saying correctly, each process should always
have 64 threads, with some just being inactive (marked by _, not .),
correct?  Or does it take a while to ramp up to this?  It seems kind of
silly to randomly sprinkle the connections through the various processes,
if there's a maximum number of spare processes set.  None of the processes
can exit then, because there's always one or two threads running around in
that process, when those threads should be all living in one process...
