which is its only caller. We need to discard the curOutPtr buffer as well,
and not count on another pass through the loop to attempt to flush it
(and raise the same failure again?).

Several socket-14.* tests failing there, and those that pass are very slow
about it. Firewall or poor networking configuration may be playing a role.

PipeWatchProc(). When we are interested in both readable and writable events of a command pipeline channel, we only want the readable from the read end of the pipe, and the writable from the write end of the pipe.

began repairing some of the logic about them. Tests iogt-2.* now fail because
they've been crafted as experiments recording the fine detail of reflected
channel driver calls, and fixing the management of channel flags is changing
that. zlib-8.5 also needed adjustment to reflect that an EOF set must come
with an empty string read when flags are functioning properly.

Large overhaul of I/O read operations
- Protects integer overflow of buffers, reusing append machinery
- Forces -buffersize changes to take place when commanded
- Uses assertions to simplify code in "can't happen" situations
- Eliminated duplication of -translation processing
- Fixes bugs io-35.18b and io-35.20

unfriendly to stacked channels, which tests for [chan push] on the trunk
help us to detect.

Back in 2011, Bugs 3384654 and 3393276 first noticed troubles with
ChannelBuffer sharing, but the magnitude of the problem wasn't truly
grasped. A fix was applied that turned out to be more of a band-aid
workaround. Now that the real fix is in place, the band-aid is actually
preventing it working properly in thie case. Rip it off!

This is not the proper final answer. ChannelBuffer management in
FlushChannel is simply not robustly correct yet.

BUFFER_READY flag serves no necessary purpose, so it is removed.
