Delphi Exception handling is definately not thread safe, and 90% of the VCL
is not thread safe including some of the thread management routines. I have
no experience with COM.

Subject: [DUG]: VCL COM Subsytem Thread Safety.


Does anybody know if the VCL COM Subsystem is thread safe?? OR if the Delphi
Exception handling is threadsafe (or not)?

Why ask? 
If I create COM controls marked as "Both" or even "Free" will the standard
VCL COM stuff handle the multiple threads?

FYI: I found that to have IIS/ASP work with a OLE/COM Object and store the
object reference in the ASP application object, that I had to aggregate the
COM Free Threaded Marshaler object.
