The difference in parsing time between single and double quotes strings is
infinitesimal and should not be a consideration in a small test file,
especially one that does a lot of forking and sleeping.
So I went for readability. IMO,
"that's all"
is much easier for the brain to parse than
q|that's all|
since the '|' character in perl isn't normally associated with string
delimiting.
The choice of single verses double-quoted is debatable. It can cause
errors either way. For example someone later modifying your version might
accidentally add:
q|that's all, $person|
while someone modifying my code might do
"that's all you get for $100"
In either case, if the programmer doesn't check the quotedness of string
before modifying it, they get everything they deserve.
