segmentation fault when running nux tests

I run:
make check
and when the tests start I get the following errors in .xtest-text-entry:
./xtest-text-entry

Further information:

The test segfaults in the signal handler for SetKeyFocusArea after calling nux::GetWindowThread. This is because the tests unsafely call directly into the program thread from the test thread, so when the signal fires, it attempts to access thread local storage that doesn't exist.

Fixing this requires some framework in nux to communicate with window threads outside of the event system.
