If someone knows a better way let me know.

1. Compile apache and this module with -g
2. start apache
3. In the apache source directory, start gdb -p <pid of _child_ apache process>
4. At the gdb prompt type: directory <source of mod_throttle>
5. Add breakpoint: break mod_throttle.c:general_html_header
6. Continue running apache: c
7. Load the page in question(*) in apache until gdb hits the breakpoint. 
  (This might take a bit depending on how many children apache currently 
has.)
8. Inspect at will. 


(*) Here is the relevent apache config I'm using, the page you want to 
test is http://example.com/throttle-users

ThrottlePolicy Volume 5M 1D
ThrottleRemoteUser 100 Volume 1M 1h
ThrottleClientIP 100 Volume 1M 1h

<Location /throttle-status>
  SetHandler throttle-me
</Location>
<Location /throttle-users>
  SetHandler throttle-remote-user
</Location>
