The comment in argp-parse.c is: If we can, we regulate access to getopt, which is non-reentrant, with a mutex. Since the case we're trying to guard against is two different threads interfering, and it's possible that someone might want to call argp_parse recursively (they're careful), we use a recursive lock if possible. I wonder what this "they're careful" means. Thanks, Marcus -- `Rhubarb is no Egyptian god.'
