Active Scripting creates Python as an out-of-process COM server.
The Active Scripting implementation should register so that inproc or
out of proc instances can be created (which is the default for all
pywin32 implemented COM objects). By default, most things which consume
script engines (eg, IE, IIS) create inproc engines.
Hence, a single OS process which creates multiple script engines is
sharing the same Python interpreter between instances.
Py_NewInterpreter is not used by pywin32's COM support. This means a
single OS process using multiple scripting engines will have each engine
instance sharing the same Python 'environment' (ie, sys.path, loaded
modules, etc). If you have control over the host and really want the
isolated behaviour, you could try explicitly requesting an out of proc
engine when calling CoCreateInstance.
