For anyone else who runs into this, there was a bug in libgcj that was causing
PyLucene to fail whenever java garbage collection was instigated. When PyLucene
was rebuilt with the patched libgcj, the problems went away.  Here's
the details:

$ ./gcj -v
Using built-in specs.
Reading specs from
/usr/local/gcc/lib/gcc/i686-pc-linux-gnu/4.1.1/../../../libgcj.spec
rename spec lib to liborig
Target: i686-pc-linux-gnu
Configured with: ./configure --disable-nls --disable-shared
--prefix=/usr/local/gcc --
with-as=/usr/local/gcc/bin/as --with-gnu-as --with-gnu-ld
--with-ld=/usr/local/gcc/bin
/ld
Thread model: posix
gcc version 4.1.1

The patch applied before rebuilding gcc 4.1.1 was:

Hope that helps!
