ExecutionTool: close output file of "--explain"

Close the OutputStream of "explanationHandler"
after the handler is uninstalled. This guarantees
that Bazel releases this file promptly, instead of
relying on the GC and finalizers to do so.

Closing streams is important to avoid stream
contention which may prevent deleting files. (Open
files may not be deleted on Windows.)

I (laszlocsomor@) am not currently unaware of any
such contention bugs in this code, but we have
seen intermittent file deletion failures on
Windows, so eliminating a potential source of such
a bug should not hurt.

Bazel

{Fast, Correct} - Choose two

Build and test software of any size, quickly and reliably.

  • Speed up your builds and tests: Bazel only rebuilds what is necessary. With advanced local and distributed caching, optimized dependency analysis and parallel execution, you get fast and incremental builds.

  • One tool, multiple languages: Build and test Java, C++, Android, iOS, Go, and a wide variety of other language platforms. Bazel runs on Windows, macOS, and Linux.

  • Scalable: Bazel helps you scale your organization, codebase, and continuous integration solution. It handles codebases of any size, in multiple repositories or a huge monorepo.

  • Extensible to your needs: Easily add support for new languages and platforms with Bazel's familiar extension language. Share and re-use language rules written by the growing Bazel community.
