I didn't run autogen.sh & configure & make in working repository, but
"svn export varnish-cache /tmp/varnish-cache".

This is diff of bin/varnishd/cache_acceptor_kqueue.c:

An update of patched varnishd: I use gdb to attach it and it looks
fine now, this is varnishstat screenshot, now it can store >5GB.
I'll try to run without gdb later.
