| 8 | * beyond that you'll have to change this too. But 1024 fd's seem to be |
| 9 | * enough even for such "real" unices like OSF/1, so hopefully this is |
| 10 | * one limit that doesn't have to be changed [again]. |

| 12 | * Note that POSIX wants the FD_CLEAR(fd,fdsetp) defines to be in |
| 13 | * <sys/time.h> (and thus <linux/time.h>) - but this is a more logical |
| 14 | * place for them. Solved by having dummy defines in <sys/time.h>. |
