it occurred to me yesterday morning that the problem with a bundle of 9p requests is that 9p then no longer maps directly to system calls.
with 9p2000, if you want to do a Tread, it's pretty clear that one needs to read(2); traditiona syscalls map directly to 9p. not so when bundles/sequences are introduced. how does a user program generate an arbitrary bundle? can programs use bundles at all without being rewritten? - erik
