[elbe-devel] [PATCH 1/1] efilesystem: Sleep after umounting /dev/pts and before umounting /dev

[Torben Hohn]

Umounting /dev fails reproducibly on the lxhb workstation.

This seem to be due to asynchronous umount behaviour. The umount of
/dev/pts is not complete, when /dev shall be umounted.

Add sleep(500ms).
