bug#18569: 24.3; Eshell: piping 'find' through 'xargs' reports random number of files

Sample eshell session:
---------------------
~/Documents/battle-field [ ] # find -L islands-page/ -name '*.bemhtml' | xa=
rgs -n1 -t | wc -l
      92
~/Documents/battle-field [ ] # find -L islands-page/ -name '*.bemhtml' | xa=
rgs -n1 -t | wc -l
      32
~/Documents/battle-field [ ] # find -L islands-page/ -name '*.bemhtml' | wc=
-l
      54
~/Documents/battle-field [ ] # find -L islands-page/ -name '*.bemhtml' | wc=
-l
      54

No other process is writing to the root folder or its
subdirectiories. Correct number of lines is 54. Works fine in *shell*,
*ansi-term*, spawned as async command or in any externall shell.

Unrelated to this issue, there's another potential bug. Adding NUL as
separator throws Emacs into infinite 'visual bell' - totally
unresponsive - can only be nuked:
--------------------------------
find -L islands-page/ -name '*.bemhtml' -print0 | xargs  -0 -n1 echo

I can't reproduce this either, seems to be the same as #25549.
