Satisfy lint by catching and re-throwing Throwable.

It would be slightly more appropriate for this class to throw a more tailored exception, but I don't think there's a suitable existing exception and this already feels very heavy for its actual use case.

This overlaps somewhat with PhutilSystem::getSystemMemoryInformation(), but that mechanism is narrower and also doesn't really work in practice, so it would probably be reasonable to remove it entirely.
