fork bomb

Someone wanted to use the old %0|%0 forkbomb a little more ... conservatively. I whipped this up:

1. @echo off
2. setlocal
3. set counter = 0
4. call :DOIT %0
5. goto :eof
6.  
7. :DOIT
8. set /a counter=%counter% + 1
9. if %counter% gtr 10 goto :EXIT
10. %1|%1
11. REM 1 ping = 1 second
12. ping -n 1 -w 1000 127.0.0.1 > nul
13. goto :eof
14.  
15. :EXIT
16. echo ran %counter% times. Exiting now.
17. endlocal

... I didn't actually run it myself, you understand. No guts, no glory system crash. But he says it 'spawned a whole lot of copies, which all self destructed'. It seems to me that since each new iteration spawns ten forks, each of which spawn 10 forks, each of which pawn ten forks ... that it would go on infinitely. But maybe, just maybe, they all share the same environment, and so ran into the same %counter% limit. I just ain't sure!
