See this freebsd-emulation thread ("can't quit matlab"):
http://groups.google.com/groups?hl=en&lr=&ie=UTF-8&oe=UTF-8&frame=right&th=206ec3e38e06e5d2&seekm=15218.39637.311548.512594_localhost.econ.vt.edu%40ns.sol.net#link1

Note that the 540e is TIOCSCTTY:

/usr/src/linux-2.2.19/include/asm-i386/ioctls.h:#define TIOCSCTTY       0x540E

Particularly look at the 3rd message in the thread that talks about the
 /dev/ptmx workaround and unix98 ptys.
If someone could solve this, it'd be great.
