This test was introduced in CL 18882, but only recently enabled as of CL 493603. It's intended to check that we don't move executing C code between threads when it re-enters Go, but it has always contained a flake. Go *can* preempt between the Go call to gettid and the C call to gettid and move the goroutine to another thread because there's no C code on the stack during the Go call to gettid. This will cause the test to fail. Fix this by making both gettid calls in C, with a re-entry to Go between them.
