In our evergreen config.yml we have two functions for uploading files after tasks complete: "upload build", to upload the results of a compile task and "upload working directory", which runs on every task to help debug a failure.

For compilation tasks, the evergreen functions "upload build" and "upload working directory" upload the current directory effectively twice. I think we can skip "upload working directory".
 
"upload working directory" includes mongodb binaries for tests. That seems excessive and unnecessary. I think we should exclude the binaries from the produced tarball.
