There's no need to copy the scripts that I can see.
merge_sleep didn't match the comments (-1 is supposed to sleep for the
load time, and we were testing against 0x01, not -1, anyway).  Add an
"int" type, and make -1 work.

Turn a couple of cascading if/else trees into switch statements.

Rework the usage complaints to match UNIX command-line patterns.
Discard support for flags (FLAG_TYPE) in the configuration API: it's
confusing (there are local flags and configuration flags in the same
CONFIG structure field) and we only use it twice.  Besides, it's not
like we're saving a lot of memory.  Turn the two uses (insert_rmw and
pareto) into booleans.
typo, needs a break.
Typo in the original help code, boolean/flag value of "0" outputs
"true".
Remove \n from descriptions, toss in a pretty-print function that breaks
on whitespace.

Split wtperf up by moving configuration functions into their own file.

Track insert operations the same way we do read and update operations.
Change populate phase to use the same operation tracking and key generation
code as the workload phase.
Show the default configuration in the help/usage output.
change g_nXXX_ops to g_XXX_ops, that 'n' is just bugging me.
Pull the table create outside the populate function (and outside the
worker, checkpoint, statistics, whatever threads).
Make checkpoints look like other threads so we can more easily monitor
them, add a "configuration_threads" configuration string, cause it to
configure checkpoints instead of "checkpoint_interval".

Don't do checkpoints during the populate phase of the run.

Minor cleanups to main routine's error handling (don't overwrite already
set error value).
Missed a checkpoint sum call.
Remove the explicit statistics cursor read/dump from stat_worker, it
can be done using WT's statistics_log configuration.
Replace the stat_worker/stat_interval function/interval pair (that
dumped out run-tracking information) with the monitor/sample_interval
function/interval pair that logs performance data at per-second
intervals.

Add new tools script to plot the output of the wtperf monitor function.

Don't free per-thread information, it could race with monitoring thread.

Merge g_util_running and g_running variables into g_stop, replace
g_threads_quit/increment with g_error/assignment, declare variables
volatile so we don't cache them.
