During development a HTTP request will pause for 1 minute ONLY when an
?index is set. This gives a realistic emulation of blocking queries.
During testing we can change this latency when we are testing blocking
queries, which we do in numerous places.
A problem can arise during testing on a very slow machine.
If you are not testing blocking queries and therefore not set a latency
to test with, if the machine you are testing on is slow enough a normal
page can assert during a test, yet not tear down before a further
blocking query request is made. This blocking query then uses the default
latency which cause the page to hang for 1 minute, which in turn causes
the test to timeout.
This only seems to happen on a very slow system, but it does potentially
explain why we occasionally see the odd flakey test popping up.
