FWIW, this turned out to be an issue with Solaris, which cannot do
buffered fopen() (which is what Python uses) on file descriptors > 256,
regardless of what the limit is set to.  The Lupy indexer failed on
indexing somewhere between 2000 and 3000 pages.

Thanks for the information, and for the advice.
