UNIX DSOs == Dynamic Shared object Library, right ? Those that need
dlopen(), dlsym(). Please correct if I am wrong.

Yep, that's right. I once had a Xerces (XML parser) dll that allocated
memory and I had to free the memory on the main program. It didn't
work till the time I told compiler to make it as a multithreaded dll.

So do we likewise need any switch for a UNIX DSOs so one can release
memory allocated by the DSO ?

Thanks.
