Yes - as far as I can see, only VMIN and VTIME change between ioctl()s.

I made two strace logs:
* strace-OK with patch segment 1 backed out
* strace-broken with patch segment 1 applied

They are trimmed at the beginning and end, and select() calls were
removed.

I'll attach a diff between the two logs, with lots of context.
Please let me know if you need anything further.
