Hello everyone, I decided to investigate this bug because I think the bug is quite irritating. After adding some ddb show commands to the source and reading a lot of code, I think I understand the problem:
The tty code doesn't leak any ucreds, it's the devfs code that crhold()'s an ucred structure. When a new pty is needed, the tty_pty code allocates a new pty. It also runs make_dev_cred(), to which it passes the thread's ucred. This function calls make_dev_credv(), which finally runs crhold(). As long as pty's have been allocated that have been created by threads in a jail, the prison structure has more references, causing the zombie jails to exist.
