Description

As seen here for example. My conjecture there was that this is due to the mutex in the lakefile.lean, but reproducing it locally it seems that there is sometimes a stray npm run build -- --tsxName <blah> process that never exits. This would suggest that the issue is actually something with NPM or Rollup.js.

Contributor guide

Research direction
Reproduce the deadlock locally on macOS, monitor stray npm processes, and check if the issue is with npm or Rollup.js by running the build steps manually.
