I really think that this is a bug, though. >=20 > It was discussed millon times already and there is at least one open > PR: >=20 > http://www.freebsd.org/cgi/query-pr.cgi?pr=3Dkern/89528 Ah, thanks Maxim. The poignant comment is: PR kern/89528: Ouch! I found a comment in tty_pty.c that it doesn't deallocate pty's anymore. Not a single destroy_dev() is called by tty_pty.c. This means the FreeBSD kernel leaks a lot of cdev's and thus ucred's and my patch is working around another bug.
