Problems with links to Percona's blog in Scalability ebook

[xaprb]

The bit.ly links in the footnote on page 14 have spurious slashes after "kernel" that break them.

The context around these is also confusing -- it's unclear that they are meant to be about rising costs of queues. As I wrote to someone:

Thanks. I'll clarify the wording around that; they are not supposed to be about Little's Law, but about the service time inflation's cause. Those blog posts illustrate what's more likely the cause in a lot of single-server systems: longer queues increase costs, e.g. lots of threads queued on a mutex causes the cost of waking up the threads to increase in InnoDB's non-native mutex implementation.
