Hi,

tcc -run usage of shared libraries depends on the behavior of the
dlfcn functions:

    tcc_add_library -> dlopen at libtcc.c:1085
    zcc_relocate -> dlsym at tccelf.c:1046
    tcc_delete -> dlclose at tccrun.c:179

I'd assume that some systems might under circumstances prefer to keep
the SO in memory even when after dlclose it's refcount drops to zero.
