dlmopen on MacOS

I have a shared library on MacOS written in FPC. It needs to be loaded multiple times, that is each time with its own set of global (dylib) variables. On Linux I would use dlmopen with LM_ID_NEWLM, but MacOS doesn't have dlmopen and dlopen doesn't have LM_ID_NEWLM. I can create a copy of the dylib on the fly and load the copy. But then the OS will complain about ObjC/ObjPascal namespace collisions, even when loading with RTLD_LOCAL. One wonders how operating systems can be designed that brainlessly. Of course, I could write my own Mach-O loader, but I have other things to do. Another idea is to prevent all use of global variables in the dylib. Before I do that, my question is if implicit compiler global variables (for the dylib code, not for the FPC runtime lib) would spoil that idea ?
