X-Git-Tag: v2.13.0-rc0~1^2~1

t3008: skip lazy-init test on a single-core box

The lazy-init codepath will not be exercised uniless threaded.  Skip
the entire test on a single-core box.  Also replace a hard-coded
constant of 2000 (number of cache entries to manifacture for tests)
with a variable with a human readable name.
