Hello all.  I am trying to use Devectorize to speed up some code i have 
written but it's having the opposite effect.  Am i doing something wrong? 
 Take this example


A = rand(1000000)
B = zeros(Float64, size(A, 1))

tic()
B = exp(A)
toc()

tic()
@devec B = exp(A) 
toc()
 

in the first exp runs in 0.02319 seconds on my machine, the second runs in 
.2664 seconds... i expected the opposite to happen!

Thank you for any help on understanding how this macro works!

Jason
