[issue9246] os.getcwd() hardcodes max path len

It's not ok to call PyMem_* functions when the GIL is released. You should only release the GIL around the call to the system getcwd().

In this case it doesn't really make a difference, since all allocations larger than 256 bytes are delegated to the system allocator.
