Hush crashes from time to time on the command: echo $(cat /proc/loadavg)
Comment 1 Denys Vlasenko 2013-01-20 22:00:36 UTC 
I set CONFIG_NOMMU=y in my .config and I can't reproduce it:

$ ./busybox hush
$ while sleep 0.01; do echo $(cat /proc/loadavg); done
<runs w/o crashing>

Looked at the patch and it does not look correct: file descriptor's status is not shared by vforked parent/child, and patch assumes otherwise.
