Setting shell-file-name to '/bin/sh' does not fix the M-x man delay 
before the [No matches] text appears in the minibuffer.

I should add to close this bug if it cannot be reproduced by someone 
on NetBSD 9.2 stable in data center grade environment on good 
hardware.

My hardware is a laptop, my SSD is 20% filled of 500Gb capacity and 
is older than two years.  The laptop is a 2006 Thinkpad x60.  I 
sometimes know how to configure the fan to keep it from reaching 
critical temperature and force shutting down.  At the moment I have 
forgotten how to.

/etc/powerd/scripts/sensor_temperature: CRITICAL TEMPERATURE! 
SHUTTING DOWN.
