While fp-stress is waiting for children to start it doesn't send any signals to them so there is no need for it to have as short an epoll() timeout as it does when the children are all running. We do still want to have some timeout so that we can log diagnostics about missing children but this can be relatively large. On emulated platforms the overhead of running the supervisor process is quite high, especially during the process of execing the test binaries. Implement a longer epoll() timeout during the setup phase, using a 5s timeout while waiting for children and switching to the signal raise interval when all the children are started and we start sending signals.

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 reStructuredText markup notation.
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.
