Note that in the end this exit (1) should be probably replaced with abort(),
so that it not only checks for correctness, but ensures that dlclose
unloads what it can. In this case all the l_opencount bumping of all the
reldep9mod{1,2,3}.so libraries was done only a) because of the dlopen
b) because of relocation dependencies in between those libraries.
This means that all 3 ilbraries should be surely unloadable at dlclose time.
