Description

Was reported in the dev thread by [e-mail]
The piece of code responsible is

for (int i = 0; i < SECTIONS_PER_CONTAINER; i++) {
. . .
   if (!Files.exists(archive)) {
        continue;
   }
. . . 
}

. . where continue happens without any delay.
It was also confirmed by Adam that small Thread.slleep(..) takes care of the problem. What puzzles me is that the loop itself has a finite end so, need to look how the parent operation is invoked.
