Proposed patch dbench to add latency and halt on space exhaustion

This patch adds a weak measure of latency (the total latency of
all the operations) and causes tbench/tbench to halt on out-of-space.
The latency figure is a good diagnostic of problems with a
benchmark- when it jumps upward, something just went wrong (;-))
This was used in the diagnosis which led to fixing the common
problem with dbench/smbtorture: if either of them run out of
disk, they produce bogus results.
