Comment (by Olly Betts):
I've made some changes which may improve this, though for me it only fails
very very rarely so I can't be very sure. These should be in 1.4.15 (once
it is release):
* 626bb0058fdcee9a30e667ebde1ae4ca66e8ff39 (cherry picked from commit
c30ec9a6ca9f1a91e0d7c160cabf280c3b1c5299)
* 399d143dd6a32913c81f782e968ba0640474232d (cherry picked from commit
f8383842183b6af604f7f066a9538754d9b263af)
* 15a48e06de22a8a23a6a2bf26d84e1329fcd595d (cherry picked from commit
d94be50772672c7bfbe120a0af7d10feb331ea42)
* 1e80e20039cd2841a2d40079e06aba21d8aa99a7 (cherry picked from commit
a171ad53225e7aaa079b0aef80790f2a24e08c44)
Feedback on whether these changes help would be useful.
If this testcase remains a bit flaky perhaps we should change it to test
the scaling behaviour for the current "large" case as the number of
repeated copies of the input query string grows (which is more like how
our other scaling testcases work) - currently it compares parsing one copy
N*M times with parsing N copies M times.
