I've merged the new parallel I/O manager that Andreas Voellmy and Kazu
Yamamoto have been working on. The new parallel I/O manager scales much
better than the current one*: the number of requests per second scales
almost linearly up to 32 cores I believe. Perhaps Andreas could post the
If you see any bugs that you think are related to the new I/O manager,
please let Andreas and Kazu know.
* The current one (which replaced an even earlier one) scaled well in the
number of open file descriptors and performed better than the I/O manager
it replaced, but it didn't scale well to multiple cores.
