+ * This allows for 1024 file descriptors: if NR_OPEN is ever grown
+ * beyond that you'll have to change this too. But 1024 fd's seem to be
+ * enough even for such "real" unices like OSF/1, so hopefully this is
+ * one limit that doesn't have to be changed [again].
+ *
+ * Note that POSIX wants the FD_CLEAR(fd,fdsetp) defines to be in
+ * <sys/time.h> (and thus <linux/time.h>) - but this is a more logical
+ * place for them. Solved by having dummy defines in <sys/time.h>.
