163a5073cb An updated Emacs cmode leads to all sorts of whitespace fixes intermixed with 
some merge changes.

254891e776 Bumping reductions manually will not be supported in future releases of the 
BEAM and has dubious value anyway.  Remove that and ignore queue depth for
now.

77e0dacdb5 Use a set of {Session, Cursor} pairs ("passes") for calls into WiredTiger 
to avoid a) opening a large number of Sessions or Cursors and b) avoid
reusing a Session/Cursor pair in more than one thread.  Each operation,
except folds, use the Session/Cursor pair corresponding to the scheduler
id (roughly "core") they are running on.  Each vnode instance will have
(count(schedulers) + count(active folds)) Session/Cursor pairs in use so
be sure to set session_max large enough when opening the connection to
WiredTiger.  This method will cause problems with scheduler threads going
to "sleep" so be sure to run schedmon to wake them up.

1129241fe0 Only open a session/cursor when first needed. There is still a race 
between vnodes during startup, ideally wterl_conn would only be opened
once.

1d6dfee192 Cache sizing is critical for performance. This change guesses at a 
reasonable setting for the WiredTiger cache size at runtime.  This cache
is shared across all vnodes regarless of how many are active at any
given time.  The algorithm is: max(1GB, 1/3 (RAM - Beam RSS size)). We don't
enable direct_io on purpose and data will be double buffered in WiredTiger's
cache and the filesystem buffer cache.  This turns out to be faster than
direct I/O despite wasting a bit of RAM.

789c44b133 Change the config to use a lsm tree rather than btree for tables. 
Stop using direct_io as it forces operations to sync more often, slowing
things down, at the expense of double-buffering (this will use more RAM).

c6eac27ea7 Start with a more rational default configuration. (Before you ask... the 
answer is 'no').  So far there has been no effort to validate that these
settings are in fact the best for Riak/KV or CS data access patterns.  These
particular settings are, at best, an educated guess based on past experience,
the docs and reading about the benchmark the WiredTiger team published here:
