Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Serialize access to debug.log stream Acquire an exclusive, advisory lock before sending output to debug.log and release it when we're done. This should avoid output from multiple threads being interspersed in the log file. We can't use CRITICAL_SECTION machinery for this because the debug log is written during startup and shutdown when that machinery is not available. (Thanks to Gavin for pointing out the CRITICAL_SECTION problems based on his earlier work in this area)
