Named pipe is only available is MySQL was configured to use one.
Named pipes are only available on the NT-derived Windows OS (which is
likely all still running) -- MySQL could be run on W9x without named
pipes, and even on WinXP my installation does not activate named pipes.

Actually, SQLite3 will happily permit multiple readers (or did, the
newest version may have a new locking scheme). However, the first
connection that seeks to write will block as long as open readers are
active, yet will also block /new/ readers. When the open readers close,
the write can complete, and then new readers can enter. Conclusion:
ensure that even read-only operations have a "commit" operation to close
