Tonight on my laptop I have been unable to get either problem
to show up on the cygwin-inst-20120504.tar.bz2 snapshot.

To get the hang to show up on the cygwin-inst-20120507.tar.bz2
snapshot.  I start a rxvt, and then 'net start sshd', putty (ssh) to the
localhost using public key trust, then ran:

  --snip
  + command procps -wwH -o pid,ppid,user,tty,args -e
  + procps -wwH -o pid,ppid,user,tty,args -e
    PID  PPID USER     TT       COMMAND
   2720     1 SYSTEM   ?        /usr/bin/cygrunsrv
   4164  2720 SYSTEM   ?          /usr/sbin/sshd -D
   3760  4164 SYSTEM   ?            /usr/sbin/sshd -D -R
   2312  3760 adm_tsr  pty2           -bash
   4664  2312 adm_tsr  pty2             -bash
   5008  4664 adm_tsr  pty2               procps -wwH -o pid,ppid,user,tty,args -e
   1320     1 adm_tsr  ?        rxvt -backspacekey ? -rv -geometry 100x33 -fn Lucida Console-16 -sr -sl 5000 -e /bin/bash --login
   5300  1320 adm_tsr  pty1       /bin/bash --login

which hangs forever.
