Add caveat for memory usage. 

This commit adds a caveat for high memory usage shown by processes with large
Bolt databases. This is expected behavior and is handled by the OS page cache.

@ -429,6 +429,13 @@ Here are a few things to note when evaluating and using Bolt:
more than 100,000 key/value pairs into a single new bucket in a single
transaction is not advised.
* Bolt uses a memory-mapped file so the underlying operating system handles the
caching of the data. Typically, the OS will cache as much of the file as it
can in memory and will release memory as needed to other processes. This means
that Bolt can show very high memory usage when working with large databases.
However, this is expected and the OS will release memory as needed. Bolt can
handle databases much larger than the available physical RAM.
