[IronPython] Announcing IronPython 2.0 RC2

[Vernon Cole]

Congratulations and "Well Done" to the Iron Python team!
This release has taken Iron Python from an experimental curiosity to a
viable work engine (IMHO).

I ran my test suite and found only one remaining restriction -- Binary data
cannot be passed as a parameter. (The same error shows up four times in
testing because six different environments are used. It passes all tests
under mySQL which does not attempt Binary.)

I am enclosing an edited copy of the test results to document the result I
found most surprising: Iron Python was faster than CPython in each test
case!

The test was set up as follows:
Workstation: A mid-range HP minitower with a dual-core 2.4GHz CPU and 2 GB
ram running XP Pro.
ACCESS database built on the local C: drive.
MS SQL database on a venerable SQL2000 server somewhere over the fiber.
mySQL on an old Ubuntu workstation under my desk.

Each test is run once with datetime.datetime dates and once with time.gmtime
dates. (Unrelated Question: Why is datetime.datetime so *much* slower???)
Then a generic test for dbapi 2.0 compliance is run.
