* elf/dl-close.c (_dl_close_worker): When removing object from
global scope, wait for all lookups to finish afterwards. * elf/dl-open.c (add_to_global): When global scope array must grow, allocate a new one and free old array only after all lookups finish. * elf/dl-runtime.c (_dl_fixup): Protect using global scope. (_dl_lookup_symbol_x): Likewise. * elf/dl-support.c: Define _dl_wait_lookup_done. * sysdeps/generic/ldsodefs.h (struct rtld_global): Add _dl_wait_lookup_done.
