Big thank you to Ralph for tracking that down and for teaching me
about strace.

Also thanks to those who reproduced the problem, which was not after
all as general my message subject had advertised.

I recall noticing years ago that Screen tends to start somewhat slowly
as a result of closing 4000 file descriptors. I never bothered to
figure out why it did this. I guess it's good that Systemd exercised
this a bit, since now we can fix a decades-old bug.
