Documentation: add caveats about I/O buffering for check-{attr,ignore}
check-attr and check-ignore have the potential to deadlock callers
which do not read back the output in real-time. For example, if a
caller writes N paths out and then reads N lines back in, it risks
becoming blocked on write() to check-*, and check-* is blocked on
write back to the caller. Somebody has to buffer; the pipe buffers
provide some leeway, but they are limited.
Thanks to Peff for pointing this out:
