[opensuse] SIGALARM blocked in Gnome-terminal
$ grep -i sigblk /proc/self/status SigBlk: 0000000000002000 SIGALRM (0x2000) is blocked in the Gnome terminal while it is not in xterm. This makes the ./configure step of a package here hang which checks for a working nanosleep(): alarm(1) = 1 nanosleep({9223372036854775807, 999999999}, ^^^^^^^^^^^^^^^^hang This is a openSUSE-13.2 guest VM under VirtualBox-4.3.26 (it was the same with VBox-4.3.24). Single-line reproducer: $ time sh -c 'sleep 10 & sleep 2 && /usr/bin/kill -SIGALRM $! && wait $!' In xterm, the first sleep process will receive SIGALRM after ~2 seconds, and terminate ... while in the Gnome-terminal, SIGALRM gets lost and the whole command line terminates after ~10 seconds.

This is a openSUSE-13.2 guest VM under VirtualBox-4.3.26 (it was the same with VBox-4.3.24).
There was a problem with nVidia drivers which set random mask; may be it is VB specific this time.

For the record, the NVIDIA issue was: https://bugzilla.novell.com/show_bug.cgi?id=855415 Maybe, I don't know since when I'm experiencing this, but it may have been since upgrading to VirtualBox-4.3.24 at the start of this month.
