On OSX 9vx consistently sigsegv panics if you quickly resize
its window a few times, particluarly before it finishes
repainting. This doesn't happen (or is hard to trigger) when
rio is not up.
Running it under gdb reveals:
Program received signal EXC_BAD_ACCESS, Could not access memory.
Reason: KERN_PROTECTION_FAILURE at address: 0x00000000

Crash on window resize seems to be not so rare but I didn't
see a solution in 5 minutes of googling.
