Eh, what does this squelch?  The sleep in the body of the loop is
silent, "test A -gt B" on the loop condition would be silent too, so
you are squelching the invocation of "$@" whose standard error
stream is already sent to 2>/dev/null?

If so, why not do it there instead?  You seem to run only "kill" to
send some signal to a process using this helper function, and it
would be silent on its standard output stream (even though it may
say "no such process" etc. on its standard error), so it is not
clear to me what you are doing with this change here...
