NSPR/NSS memory leak

Hi All,

I have a dll in Windows which uses NSS 3.11.4 and NSPR 3.6.4.
The dll does a PR_Init during Load.

Now, I have an application(.exe)which loads this dll dynamically using
LoadLibrary and then unloads it using FreeLibrary.
So after LoadLibrary and FreeLibrary I expect NO memory leak in my
application.

But however i see an increase of 2 threads the moment a call to
PR_Init is made. And also there is a memory leak of 4K after
FreeLibrary.

Can anybody guess if the NSPR library is completely deinitialized and
removed from memory when my above program calls FreeLibrary???? I
believe this should be the case.

Also, If i call PR_Cleanup as part of my FreeLibrary(Dll Unload)
routine, then the whole application just hangs????

Can anyone help me out here!

Thanks
Vinu
