ok, so this doesn't help.

sorry, my mistake, I've rerun with -DONE_PROCESS
(gdb)
Starting program: /home/stas/httpd/2.0/bin/httpd -DONE_PROCESS
the plain httpd is available for serving almost immediately (takes about

oh, never mind, I just thought that instead of pasing the fh around,
we could just throw the content in. not much gain just simpler. it doesn't
fix anything otherwise, I've used a wrong word.
