There are two memory monitor tests that use Python's unittest module directly,
but GLib tests should be outputting TAP. Use the embedded TAPTestRunner to
ensure that TAP is output for these tests too.
Distributions will likely want to update GLib before
GObject-Introspection, to avoid circular dependencies.

The loops should continue iterating if the timeout is non-zero and we're
still waiting for the updated value. Otherwise, if things break, we'll
be waiting until we receive a value that never arrives.
Those tests require Python, gobject-introspection and python-dbusmock
making them unsuitable to be run within the uninstalled test suite.
There are no restrictions of dependencies when it comes to installed
tests so use those to exercise GMemoryMonitor.
