Loosely related anecdote (I feel like telling because this particular
phenomenon should really be documented for its example value): Some
years ago, I used the time between Christmas and New Year's Eve for
investigating a network driver which occasionally caused serious
performance issues customers had been complaining about in an
on-and-off way for one or two years. The code was a pretty typical
example of a 'vendor written "board support" device driver' (judgeing
from the comments, it originally targetted SVR4, had been sort-of
ported to every other operating system under the sun, and was supposed
to support countless generations of wildly incompatible hardware),
that is, a total mess even the people who worked on it didn't
understand anymore.  One of the rather harmless 'strange sights' I
found in there was that the RX DMA ring[*] was indexed using a
variable named index while the TX ring used an outdex.

[*] Array treated as ring buffer with the help of index = (index + 1)
% ring_size stepping code used to inform the DMA (direct memory
access) engine on the NIC of the locations of memory buffers set aside
for storing incoming ethernet frames or picking up outgoing ones. The
R in RX stands for reception, the T in TX for transmission. The
acronyms are conventionally used in this way.
