Possible issue building kernel modules: dialog4ports invocation

[David Wolfskill]

This morning, my laptop & build machine (daily) source-based updates
for stable/11 were uneventful, but the (weekly) update to my desktop
at work died (temporarily) during an attempt to build a kernel
module (because I have

	PORTS_MODULES=x11/nvidia-driver

in etcsrc.conf):

...
--- kernel.full ---
linking kernel.full
ctfmerge -L VERSION -g -o kernel.full ...
      text      data       bss        dec         hex   filename
  22011101   1257388   4963232   28231721   0x1aec829   kernel.full
--- kernel.debug ---
objcopy --only-keep-debug kernel.full kernel.debug
--- kernel ---
objcopy --strip-debug --add-gnu-debuglink=kernel.debug  kernel.full kernel
--- all ---
===> Ports module x11/nvidia-driver (all)
cd ${PORTSDIR:-/usr/ports}/x11/nvidia-driver; env  -u CC  -u CXX  -u CPP  PATH=/
usr/obj/usr/src/tmp/legacy/usr/sbin:/usr/obj/usr/src/tmp/legacy/usr/bin:/usr/obj
/usr/src/tmp/legacy/bin:/usr/obj/usr/src/tmp/usr/sbin:/usr/obj/usr/src/tmp/usr/b
in:/sbin:/bin:/usr/sbin:/usr/bin:/usr/local/bin:/usr/local/sbin  SRC_BASE=/usr/s

amd64/bmake -B clean all
===>  Cleaning for nvidia-driver-367.44_3
*** [all] Stopped -- signal 22
....

Running "ps" showed that a few processes (including dialog4ports)
had received SIGSTOP; sending them a SIGCONT wasn't helpful (as in
"didn't seem to cause the processes to resume execution").

I finally did circumvent the issue by (separately) running "portmaster
x11/nvidia-driver", which brought up the dialog4ports menu Just Fine,
then built & installed the port.

After having done that, build kernel (including updating the
x11/nvidia-driver module again), install kernel, install world (as
well as mergemaster &c.) all worked.

In case it's relevant, I ran the build within script(1), running
in a tmux(1) session.

Peace,
david
