+telnetd: Fix deadlock on cleanup
+
+the patch comes from:
+https://bugs.launchpad.net/ubuntu/+source/netkit-telnet/+bug/507455
+https://launchpadlibrarian.net/37882973/0001-telnetd-Fix-deadlock-on-cleanup.patch
+
+The cleanup function in telnetd is called both directly and on SIGCHLD
+signals. This, unfortunately, triggered a deadlock in eglibc 2.9 while
+running on a 2.6.31.11 kernel.
+
+What we were seeing is hangs like these:
+
+  (gdb) bt
+  #0  0xb7702424 in __kernel_vsyscall ()
+  #1  0xb7658e61 in __lll_lock_wait_private () from ./lib/libc.so.6
+  #2  0xb767e7b5 in _L_lock_15 () from ./lib/libc.so.6
+  #3  0xb767e6e0 in utmpname () from ./lib/libc.so.6
+  #4  0xb76bcde7 in logout () from ./lib/libutil.so.1
+  #5  0x0804c827 in cleanup ()
+  #6  <signal handler called>
+  #7  0xb7702424 in __kernel_vsyscall ()
+  #8  0xb7641003 in __fcntl_nocancel () from ./lib/libc.so.6
+  #9  0xb767e0c3 in getutline_r_file () from ./lib/libc.so.6
+  #10 0xb767d675 in getutline_r () from ./lib/libc.so.6
+  #11 0xb76bce42 in logout () from ./lib/libutil.so.1
+  #12 0x0804c827 in cleanup ()
+  #13 0x0804a0b5 in telnet ()
+  #14 0x0804a9c3 in main ()
+
+and what has happened here is that the user closes the telnet session
+via the escape character. This causes telnetd to call cleanup in frame
+the SIGCHLD signal is delivered while telnetd is executing cleanup.
+
+Telnetd then calls the signal handler for SIGCHLD, which is cleanup().
+Ouch. The actual deadlock is in libc. getutline_r in frame #10 gets the
+__libc_utmp_lock lock, and utmpname above does the same thing in frame
+
+The fix registers the SIGCHLD handler as cleanup_sighandler, and makes
+cleanup disable the SIGCHLD signal before calling cleanup_sighandler.
