Tobin Baker senderista

As tested on Linux:

An SCM_RIGHTS ancillary message is "attached" to the range of data bytes sent in the same sendmsg() call.
However, as always, recvmsg() calls on the receiving end don't necessarily map 1:1 to sendmsg() calls. Messages can be coalesced or split.
The recvmsg() call that receives the first byte of the ancillary message's byte range also receives the ancillary message itself.
To prevent multiple ancillary messages being delivered

Internet Scale Services Checklist

A checklist for designing and developing internet scale services, inspired by James Hamilton's 2007 paper "On Desgining and Deploying Internet-Scale Services."

http://mvdirona.com/jrh/talksandpapers/jamesrh_lisa.pdf

Basic tenets

Does the design expect failures to happen regularly and handle them gracefully?
Have we kept things as simple as possible?

Update HISTORY.md
Commit the changes:

git add HISTORY.md
git commit -m "Changelog for upcoming release 0.1.1."

Update version number (can also be minor or major)

	// Remarks:
	// * Implements composite writer mutex and seqlock in a single word-sized lock.
	// Allows optimistic reading and pessimistic writing.
	// Readers don't write to shared synchronization metadata, which helps avoid
	// coherence traffic. Readers must tolerate observing inconsistent state, however.
	// * Writer mutex is based on LIFO-CR lock from http://arxiv.org/abs/1511.06035.
