hcm@ do they need to be CCed on this? I think this is exepected behavior on my fuzzer.

I'm OK with being taken off this bug, but since it is in an area of code I'm interested in, curiosity got the better of me and I did some debugging. A small rectangle is turned into a region through a matrix which causes the region to be very large. SkPathRef::makeSpace attempts to allocate 1G of memory; when running under GDB on Linux, I get an "out of memory" assert shortly thereafter. I suspect that with infinite resources, the function would run a very long time but would eventually succeed. As the author suggests, the timeout is the expected behavior.
