This takes 524ms over here (Intel core 2 duo, 2.4 MHz)

Is that "approximately forever"?

If your results are much worse, consider attaching the debugger log
(contents of the right pane of Windows->Views->Debugger Log)

[If you expand a char[10000] (i.e. really an array of 10000 chars,
not something that's displayed as C-style string), there are 10000
child entries of the form '{value="48",},' generated, i.e. closer
to 130k of data. Still not much, but I don't think the time is 
unreasonable either]
