Comment (by strk):

 With the patch the performance between 2.2.0 and 2.1.9 are back comparable
 (2.2.0 being actually faster):
 {{{
 -- limit 10k offset 20k  real    3m48.034s [2.1.9dev] addLinestring
 postpatch
 -- limit 10k offset 20k  real    3m3.227s  [2.2.0dev] addLinestring
 postpatch
 }}}

 Don't ask me how I previously handled to see 2.1.9 taking ~2 minutes,
 maybe I was just tired and did something stupid like running a modified
 version.
