-dnl Setting thread names
-dnl ~~~~~~~~~~~~~~~~~~~~
-dnl The portability situation here is complicated:
-dnl
-dnl * FreeBSD supports pthread_set_name_np in <pthread_np.h>
-dnl   and (if not _POSIX_SOURCE) pthread_setname_np() in <pthread.h>
-dnl   because of the conditional visibility, we prefer the former.
-dnl * glibc supports pthread_setname_np
-dnl * Darwin supports pthread_setname_np but does not take a
-dnl   pthread_t argument.
