Author: ed Date: Wed Oct 20 09:35:20 2010 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.
