Test speed vs. effectiveness

[Patricia Shanahan]

The investigation that revealed problems in outrigger's FastList and 
some of the corresponding test code started from a single failure of a 
QA test that usually runs correctly. The failure did not reproduce with 
the test as currently checked in. To investigate, I had to drastically 
increase the numbers of entries and threads.

Should I check in more stressful versions of some or all of the 
outrigger stress tests?

Doing so would further slow down QA, by order minutes for each enhanced 
test. On the other hand, I have clear evidence that the current versions 
of the tests have low probability of finding concurrency bugs that could 
be detected by enhanced versions.
