[pypy-commit] pypy more-rposix: Don't use os.write in gc helper functions.

Log:	Don't use os.write in gc helper functions. This fixes a test where
	os.write is not used in translated function, and is annotated too
	late.

	extfunc.py uses a "mixed-level delayed object" but I don't know how
	to do this here.
