When testing reset, we wait for 1s on the main thread for the hang to start. Meanwhile, we continue submitting requests on all the background threads, and we may have more threads than cores and so potentially starve the waiter from being woken within the timeout. As the hang timeout and the active timeouts are the same, it is hard to distinguish which caused the timeout. Bump the active thread timeouts to 5s, compared to the 1s timeout for the hang, so that we preferentially report the hang timing out, while hopefully ensuring that we do at least wake up the hang thread first before declaring the background active timeout.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
