GNU Parallel Bug Reports Bug report: combining --timeout and -u

[paralleluser]

Dear Ole,

If you combine --timeout and -u the following happens.  If you take away either 
--timeout or -u the bug goes away.  Interestingly, the bug will show even if 
you use --dry-run, and occurs during the dry run.

Take either --timeout or -u away and it works fine.
Keep --timeout and change -u for --linebuffer, or --group, or --keep-order ... 
and in all those cases it works fine.

parallel -V
GNU parallel 20170322

seq 3000 | parallel --dry-run --timeout 3600   -u    --jobs 30 

gives this:
