The "one" script has a bashism that causes a race condition when /bin/sh isn't bash.

It does this:

kill cat $ONE_PID &> /dev/null
kill cat $ONE_SCHEDPID &> /dev/null

...and removes the PID files immediately afterwards.

"foo &> bar" in bash is equivalent to "foo > bar", but in dash, it's equivalent to "foo > bar &", so "kill" and "rm" race to get to the PID file first. Every once in a while, rm wins and you get something like:
kill: 147: Usage: kill [-s sigspec | -signum | -sigspec] [pid | job]... or
kill -l [exitstatus]

..and either the scheduler or oned is still running.

The attached patch fixes this problem.
