See the attached program; on my machine, its output is
as described therein.  That is: if a bsddb hash
database is opened read-only, and has never been opened
for writing (except when first created), then calling
len() on the database object returns the correct value
the first time, but zero on the second and later calls.
 Opening the database for writing once seems to
eliminate the problem; even when it is opened read-only
later, len() behaves as expected.

My machine runs Linux 2.6.16, glibc 2.3.4, Python
2.4.3, and Berkeley DB 4.3.28.

Greg, is this a known issue?  Any ideas?

into it.
