Creating files with Upload() in Parallel threads causes md5 and chunk errors.

This unit tests fails with MongoDB.Driver.MongoCommandException : Command 'filemd5' failed: exception: chunks out of order (response:

{ "errmsg" : "exception: chunks out of order", "code" : 10040, "ok" : 0.0 }

).

The server complains that:

NOTE: I I changed MaxConnectionPoolSize in MongoDbServerSettings to 1, meaning only a single connection can be alive at once, this error does not occur.

I'd also like to point out that using ThreadPool in the C# Connection Manager seems like a bad idea seeing as this ThreadPool is static and shared with everything else in the system allowing any code in the system to essentially "lock out" the WaitCallback's.
