Sequencer.mt fix 1 (!26569) · Merge requests · atlas / athena · GitLab

Marcin Nowak requested to merge mnowak/athena:seqencer.mt.fix1 into master Sep 13, 2019

Fixes to the new MT event ranges processing:

make threads=1 case work by treating it like a single process event sequences
disable concurrent writing of ranges because metadata writing was corrupting files sometimes (hopefully just a temporary change)
