Try these:

	varnishtop -i url

	varhishtop -i header -C -I '^user-agent:'

	varhishtop -i header -C -I '^user-agent:' -X MSIE

	varhishtop -i header -C -I '^user-agent:.*MSIE'

	varhishtop -i header -C -I '^user-agent:.*java'

You can also run them on the logfiles from the live test:

	zcat _vlog21.gz | varnishtop -r - -i header ...

Add function VSL_OpenStats() which directly returns a pointer
to the varnish_stats structure.

Add opaque VSL_data structure as handle to the log-tailer functions.

Add generic argument parsing function for all log-tailers.

Add support for generic "-r <file>" option.

Assign prefix WRK to the worker pool.

Introduce a struct workreq since the prefetcher (when it happens) will
not have a session to pass in.

The worker threads get a cond_var each and are hung from a list in
most recently used order.

When a request is queued and the worker thread list is not empty,
tickle the cond_var of the first one.

If no threads were availble the max number of threads is not reached,
try to start another worker thread.

If the max was reached or the start filed (likely due to out of memory)
indicate overflow and let the existing pool deal with it.

Create only the minimum requested number of threads initially.

Allow specification of the timeout before a dynamic worker thread commits
suicide to be specified with -w.

Default parameters are -w1,UINT_MAX,10 {min, max, timeout}

Avoid calling getaddrinfo() for every connect by catching the result
in the backend structure.

Minimize number of socket/connect calls by caching the last good
address in the backend structure.

If all addresses in the cached getaddrinfo() result fails, call
getaddrinfo() again (to catch DNS changes) and try the list again.

cache_shmlog.c contains stuff for both cache and mgt, so remove the
cache_ prefix.

Rename cache_shmlog.h to common.h and put joint stuff there.
