[Bug classpath/28939] New: FileChannelImpl.write hangs forever writing to NFS file |

I just installed PyDev on Eclipse 3.2, running on JamVM, and configured it to
use the python interpreter at /usr/bin/python in the Eclipse prefs dialog. When
I clicked OK in the prefs dialog, PyDev then scanned for all python code on the
PYTHONPATH, and then eclipse hung at the end of that process. A CTRL+\ showed
that it's hanging while serialising some kind of data structure:
