Test case

Description of Problem:

My test case creates an HttpWebRequest to local webserver and POSTs several
megabytes. This is done repeatedly. Under mono the test quickly consumes all
available memory. Under .NET the test never consumes more than 45mb of RAM.

Steps to reproduce the problem:
1. gmcs test.cs
2. mono test.exe
3. Keep an eye on process memory usage in top / taskman.


Actual Results:
All available physical memory is consumed by the process.


Expected Results:
Memory usage ought to stabilize somewhere reasonable.


How often does this happen? 
Always.


Additional Information:
My primary test used Mono 1.9 under Mac OS X 10.5. 
I also tested using Mono 1.9.1 under Windows XP with similar results.
