priocntl workaround for Solaris 9 pty-close bug
Implement gross hack to use priocntl to work around the Solaris 9
pty-close bug. Run expect at a higher class "FX" priority than
spawned processes, which run at a lower class "FX" priority. "make
check" needs to start from a process which has FX priority >= 30 and
FX priority limit >= 30. Thanks to Bill Sommerfeld for the hints.
