We are seeing a serious memory leak in our production servers after upgrading
to the bits from the 2.4 branch. We did not see this leak in the 2.4-0
(revision 12xxxx) and prior. 

Attached is an isolated repro on the recently release 2.4.2 bits.

Reproducible: Always

Steps to Reproduce:
1. extract the attached archive to /root/monoleak
2. chown -R www-data:www-data /root/monoleak
3. copy /root/monoleak/monoleak to /etc/apache/sites-enabled/monoleak
4. ab -n 2000000 -c 50 http://localhost/
5. look at the memory usage of the mono process in top
Actual Results:  
Memory consumption continues to rise reaching 

Expected Results:  
memory consumption to remain flat.
