I cannot remember specific references now but when I looked into this before it is because the official 2.x line is compiled using VC9. When memory is passed between applications relying on different version of the CRT then you can end up with hard to diagnose memory corruptions that eventually cause problems.

Digging a bit I found this thread [1] that highlights a similar CRT issue in python modules such as psycopg2 (which I use for PostGreSQL) that use the CRT internally...

If you can guarantee to me that isn't going to happen then it would make my life easier!
