I've written two versions of a prime number sieve, and I'm trying to
figure out how to performance test them. I've found functions to get
the current date and time, and to subtract them, but when I put them in
a do notation, I guess the laziness or something, makes the calculation
happen

High-performance parallel programs are hard to write.
This is in part an answer, in part a question. If 'b' is a simple
value, then somethign like:
timer f a = do
t1 - get current time
t2 - f a `seq` get current time
return (different in t2 and t1)
(my memory of Time fails right now, so fill in the proper functions.)
perhaps safer is to use
timer f a = do
t1 - get current time
evaluate (f a)
t2 - get current time
return (different in t2 and t1)
where evaluate is from Control.Exception. could someone tell me how
evaluate compares to seq and deepSeq?
The documentation explains the difference, but it's a bit cryptic.
I'm trying to figure out how to use the POSIX function utime. I'm pretty
much stumped at the moment, largely because I can't figure out how to do
anything useful with ClockTime variables.
I can't see any way to make use of GHC.Posix.utime, as it gives a binding
to the utime function, but the
