This will open the door for us to drop `tie' usage from
ProcessIO completely in favor of OO method dispatch. While
OO method dispatches (e.g. `$fh->close') are slower than normal
subroutine calls, it hardly matters in this case since process
teardown is a fairly rare operation and we continue to use
`close($fh)' for Maildir writes.

On my x86-64 machine, OpenSSL SHA-256 is nearly twice as fast as
the Digest::SHA implementation from Perl, most likely due to an
optimized assembly implementation. SHA-1 is a few percent
faster, too.

Some code paths may use maximum size checks, so ensure
any checks are waited on, too.

Using "make update-copyrights" after setting GNULIB_PATH in my

This will make it easier to show parameters used for testing
and potential tweaks to be made.

This ought to improve overall performance with multiple clients.
Single client performance suffers a tiny bit due to extra
syscall overhead from epoll.
This also makes the existing async interface easier-to-use,
since calling cat_async_begin is no longer required.

I didn't wait until September to do it, this year!

I somehow thought "foreach (<$cat>)" could work like
"while (<$cat>)" when it came to iterating over file
handles...

This is a transitionary interface which does NOT require an
event loop. It can be plugged into in current synchronous code
without major surgery.
It allows HTTP/1.1 pipelining-like functionality by taking
advantage of predictable and well-specified POSIX pipe semantics
by stuffing multiple git cat-file requests into the --batch pipe
With xt/git_async_cmp.t and GIANT_GIT_DIR=git.git, the async
interface is 10-25% faster than the synchronous interface since
it can keep the "git cat-file" process busier.
This is expected to improve performance on systems with slower
storage (but multiple cores).
