Line 125 of multiprocessing.c is "*CMSG_DATA(cmsg) = fd;".  CMSG_DATA returns an unsigned char*, while fd is an int, so this code does not support file descriptors > 256 (additionally, I'm not sure if the buffer is guaranteed to be initialized with zeros).   recvfd has an analogous problem at line 168.  Both of these need to be changed to copy the entire integer, e.g. by casting the result of CMSG_DATA to an int*.
