Build feature freezes on Windows

[efoerster]

The build feature freezes frequently on Windows. This can be reproduced by saving the the document and build it directly afterwards. The workaround for this issue is to use the server when it freezes e.g. by editing the text document. This causes the build to continue normally.

The issue seems to be related to the Windows specific process event handling of the tokio-process crate. It would be good to have a small reproduction example to submit this isssue to the repo. Any help is greatly appreciated.
