Bug 431

Summary:	sudo -s in 1.7.4 with HAVE_PAM forks and waits but child bash hung after suspend

Description SBertilson 2010-08-24 00:59:22 MDT

HAVE_PAM activates CMND_WAIT which causes a fork/exec rather than a pure exec.  When I "suspend" the resulting bash session and try "fg" to bring it back, the sudo continues, but the bash remains stopped.  If I SIGCONT the bash, it works fine until the next suspend.

Patch to pass on SIGCONT when sudo resumes after suspend

I've attached a patch which fixes this.  It will be part of sudo 1.7.5.
