+   This macro is similar to SYSCALL in asm.h, but not completely.
+   There's room for optimization, if we assume this will continue to
+   be assembled as one file.
+
+   This macro expansions does not include the return instruction.
+   If there's no other work to be done, use something like:
+       SYSCALL(foo) ; ret
+   If there is other work to do (in fork, maybe?), do it after the
+   SYSCALL invocation.  */
