When I have any compilation error(s) there is a rather long delay (around 14s on my machine) before rustc finally exits. Successful compilation is very fast. I am on Ubuntu 16.04 in VMware Workstation 12.5 for Windows virtual machine. Steps to reproduce: ``` $ touch test.rs $ time rustc test.rs error: main function not found error: aborting due to previous error real 0m13.423s user 0m13.276s sys 0m0.112s ``` ## Meta `rustc --version --verbose`: ``` rustc 1.14.0-nightly (3f4408347 2016-10-27) binary: rustc commit-hash: 3f4408347d2109803edbf53c89c8bce575de4b67 commit-date: 2016-10-27 host: x86_64-unknown-linux-gnu release: 1.14.0-nightly LLVM version: 3.9 ```
