You're running this in sh? But reporting it as a bug in bash?

I ran this, with #!/bin/bash and with sleep 1 instead of sleep 0.1,
on an HP-UX 10.20 system and a Debian 6.0 (Linux) system. For me,
it printed "DONE" once per second until I pressed ctrl-C, on both
systems.
Changing the sleep 1 back to sleep 0.1 and re-running on the Linux
system produced the same result, just 10 times as fast.
Changing the #!/bin/bash to #!/bin/sh and re-re-running on Linux
still produced the same result.
