Hi,

For your information, just out of curiosity, I tested Wolfgang's code
\starttext
\count0=0
\loop\ifnum\count0<3986 % try 3987
  \advance\count0 by 1
  \shipout\vbox{}
\repeat
\end
\stoptext

which works fine with 3986 pages but not with 3987 pages and above.
This is with mkiv, version: 2011.02.25 22:03, and LuaTeX version beta-0.65.0-2010121316
on Mac OS X 10.6.6.

Best regards: OK
