Re: [Libguestfs] [PATCH libnbd v3] lib/errors.c: Fix assert fail in exit path in multi-threaded code

This causes a different problem. We actually hit the problem in this test: https://gitlab.com/nbdkit/libnbd/-/blob/master/tests/dlopen.c (1) The thread calls dlclose(), unmapping the library but leaving the pthread_key_t in place, which contains a pointer to free_errors_key in the unmapped library. (2) The thread exits, and glibc calls free_errors_key, causing a crash. Maybe -z nodelete really is the only answer.
