The next shell started, on the next available pseudoterminal, will work without problems. The `term` on `p6` has already been running before: # ps -Af | grep [t]typ6 root 6871 3 - 5:45.86 /hurd/term /dev/ptyp6 pty-master /dev/ttyp6 In this situation, `w` will sometimes report erroneous values for *IDLE* for the process using that terminal. Killed that `term` instance, and things were fine again. All this reproducible happens while running the [[GDB testsuite]]. --- Have a freshly started shell blocking on such a `term` instance. $ ps -F hurd-long -p 1766 -T -Q PID TH# UID PPID PGrp Sess TH Vmem RSS %CPU User System Args 1766 0 3 1 1 6 131M 1.14M 0.0 0:28.85 5:40.91 /hurd/term /dev/ptyp3 pty-master /dev/ttyp3 0 0.0 0:05.76 1:08.48 1 0.0 0:00.00 0:00.01 2 0.0 0:06.40 1:11.52 3 0.0 0:05.76 1:09.89 4 0.0 0:05.42 1:06.74 5 0.0 0:05.50 1:04.25 ... and after 5:45 h: $ ps -F hurd-long -p 21987 -T -Q PID TH# UID PPID PGrp Sess TH Vmem RSS %CPU User System Args 21987 1001 676 21987 21987 2 148M 2.03M 0.0 0:00.02 0:00.07 /bin/bash 0 0.0 0:00.02 0:00.07 1 0.0 0:00.00 0:00.00 $ ps -F hurd-long -p 1766 -T -Q PID TH# UID PPID PGrp Sess TH Vmem RSS %CPU User System Args 1766 0 3 1 1 6 131M 1.14M 0.0 0:29.04 5:42.38 /hurd/term /dev/ptyp3 pty-master /dev/ttyp3 0 0.0 0:05.76 1:08.48 1 0.0 0:00.00 0:00.01 2 0.0 0:06.41 1:11.90 3 0.0 0:05.82 1:10.28 4 0.0 0:05.52 1:07.06 5 0.0 0:05.52 1:04.63 $ sudo gdb /hurd/term 1766 [sudo] password for tschwinge: GNU gdb (GDB) 7.0-debian Copyright (C) 2009 Free Software Foundation, Inc.
