Thanks a lot! Even if this is officially more a bug in systemd than a
bug in rustc, it's always a good thing that error messages are helpful
and explain what's the problem.

Yes, or just wait for syetemd 229-6 to enter testing.

The old default for TasksMax was not good for everybody (this FTBFS
problem is an example) so they have set it to infinity in systemd.

So I did the same in my hand-made autobuilder (which is triggered by
cron) to avoid this happening again.

Thanks.
