Technically saying `tty.ReadStream#setRawMode()` is correct,
but since a typical use cannot instantiate `tty.ReadStream` themselves,
and 99% of the time the only instance is `process.stdin`,
then a little clarification seemed necessary.

Travis-CI is failing on this test repeatedly, but other Linux systems
seem to be fine with it.  Alter the logging so it's more clear which
part is timing out.

Said test takes over 90 seconds on my Core 2 Duo which is too long, even for
the pummel tests.

Instead of allocating a new 64KB buffer each time when checking if there is
something to transform, continue to use the same buffer. Once the buffer is
exhausted, allocate a new buffer. This solves the problem of huge allocations
when small fragments of data are processed, but will also continue to work
well with big pieces of data.

The test is too slow / CPU intensive for the main test harness.

Said test adds little value and only serves to annoy me when moving around
modules. It was broken anyway: it passed inside the test runner and failed
when run from the command line thanks to the environment sniffing it did.

Reduces the executable's size by a few kilobytes.

This reapplies commit c781f177
This reverts commit 00224771

Prevents alignment issues when people create a typed array from a buffer.
Unaligned loads or stores are less efficent and (on some architectures) unsafe.
