Seen the same problem with large test runs. My theory is the following. Memory exhaustion in this case is due to the fact that MSTest test result files are XML. Therefore it needs to keep all the log results in memory until the end of the test run before serializing to disk. Hurray for XML :-)

I have posted this problem as a connect issue a while back and it should have been fixed in MSTest 10 (going 64 bit) but I haven't been able to verify this yet because of all the other problems we have moving to VS2010 and .NET 4.0.
