Issue with your sample code

[Dean]

Hello,

I would like to report one issue with sample code on your page, or
rather with the simpleHttpServe function it is indirectly calling.

http://snapframework.com/docs/tutorials/snap-api

When I load your sample into cabal repl it works but only the first
time. If I break out of the main loop with Ctrl+c and try to run it
again I get error that is pasted at the end of this email. I tested this
under Windows 8.1, ghc 7.8.4, snap-0.14.0.6-808, snap-core-0.9.8.0-24,
snap-server-0.9.5.1.

Code is not closing log file handles that it opens when I break out of
the loop with C-c. This is unfortunate because it makes it impossible to
use cabal repl for development to speed up write-compile-run cycle.
Interpreter has to be restarted after every change which defeats the
purpose of using it.

I took a quick look at your code and it seems that simpleHttpServe is
trying to handle this with withLoggers function but I couldn't yet
figure out why it isn't working.

Kind regards,

Dean Kostadinović
