Sequentialize the calls to CheckResourceIntegrity

This CL is adding a sequence to run all the calls to
CheckResourceIntegrity in sequence instead than in parallel.

The main reason is to avoid Shutdown hangs where all the worker
background threads are stalled on a Read(...) and won't allow
the scheduler to dispatch remaining BLOCK_SHUTDOWN tasks.

Logo Chromium

Chromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web.

The project's web site is https://www.chromium.org.

To check out the source code locally, don't use git clone! Instead, follow the instructions on how to get the code.

Documentation in the source is rooted in docs/README.md.

Learn how to Get Around the Chromium Source Code Directory Structure .

For historical reasons, there are some small top level directories. Now the guidance is that new top level directories are for product (e.g. Chrome, Android WebView, Ash). Even if these products have multiple executables, the code should be in subdirectories of the product.
