Summary: adodbapi - Subtle crash

Initial Comment:
There is a subtle crash that can occur related to time.sleep(>10) and adodbapi.connect() calls, the second time will crash,
attached there is the simplest test case to crash it and various comments explaining the crash behavior test enviroement and stacktraces.

i hope will be useful to find the right solution, i've only found a bad workarond, without calling adodbapi.close() the crash doesn't happens.

thank you in advice

fixed by removing CoUninitialize() and removing reference to Dispatch
structure after closing.

Message:
Crash duplicated on Windows Vista 32 bit with SQL Server (local).
Does NOT crash in IronPython, indicating that this is probably a pywin32
error.
Investigation continues.

Message:
The connection string needs sqlserver express installed on the machine, but
the same happens also with oracle oledb provider, this are the two
providers i've tested on, but could be the crash occurs with any provider

Message:
I haven't had a chance to repro this yet as the connection string doesn't
work on my dev box.
