New Revision: 214105
URL: http://svn.freebsd.org/changeset/base/214105

Log:
  Remove setpgid() call before executing child process.
  
  Using a separate process group here is bad, since (for example) job
  control in the TTY layer prevents interaction with the TTY, causing the
  child process to hang.
