Data.ConnectionPool.Internal.ConnectionPool

Internal packages are here to provide access to internal definitions for library writers, but they should not be used in application code.

Preferably use qualified import, e.g.:

 import qualified Data.ConnectionPool.Internal.ConnectionPool as Internal

This module doesn't depend on streaming-commons and other non-HaskellPlatform packages with notable exception of resource-pool. Another notable thing is that this package is not OS specific. Please, bear this in mind when doing modifications.
