Graceful seems to be really broken.
after 4 days of use we have ~100 000 lines in error_log stating:
[Sat Jan 01 23:12:52 2011] [warn] long lost child came home! (pid 32616).
This happens right after graceful restart.
The new peruser was installed 31 dec. and graceful restart was done few
hours later. 4 days later there were no new graceful restarts or regular
restarts.
Yesterday the apache hung and wasn't responding anymore.
We have ~150 vhosts.

Hi,
I've made a few changes, so here is another update (v4). Probably the last, for
while. :-)
Changes (from RC2):
* (v4) Code cleanup
* (v4) Performance: childs are started in ~25ms, 40 times faster than in RC2
(~1000ms)
* (v4) Bug fixed: now checking if total_processors is 1 (first access) to start
StartProcessors
* (v3) Performance: new child type (CHILD_TYPE_RESERVED) to avoid collision (2
childs trying to get the same free slot)
* (v3) Bug fixed: fixed a bug in RC2, wait_timeout was always 0, never sleeping
to wait for new workers.
* (v2) Performance: StartProcessors, new configuration directive to control the
number of child processors per vhost at startup
* (v2) Performance: childs are started in ~50ms, 20 times faster than in RC2
(~1000ms)
* (v1) Performance: faster to lookup for free slots (this is important on busy
servers, with many virtual hosts)
* (v1) Performance: faster to count processors, one single loop counts all
processors
* (v1) Bug fixed: bug when MinSpareProcessors is set to 0 (now all workers
processes are killed when idle_timeout is reached)
* (v1) Bug fixed: Free-up slots when a WORKER or PROCESSOR unexpectedly dies
