+                When using pthread_attr_t (this path we're in now), the default stack size seems to be too small. If the
+                pthread_attr_t path is skipped entirely, things work fine. It looks like skipping the call to
+                pthread_attr_setstacksize(), which happens when stackSize is 0, the chosen stack size is smaller than
+                what it would be if we skipped the pthread_attr_t path.
+
+                There are two work arounds for this. The first is to always skip the pthread_attr_t path. The second is
+                to have a specialized path here for Vita and explicitly default to something bigger. I'm doing both.
