I'm using a list of objects that each needs to load a shared Library (written in C). As some operations inside the library are slow, I've created a TThread to do multiple operations simultaneously. As the library is not thread safe, I thought using "loadLibrary" will create a different "instance" after each load, but, as the TLibHandle resulting of that function is the same, I think the library is only loaded once. Is there a way to have different handles for each loadlibrary?.

No, you can load a library only once per process. Loading it more than once is not supported by any dynamic linker I know of, because it would result in symbol clashes.
