New submission from Alex Gaynor <alex.gaynor at gmail.com>:

Now that we've moved map() to app-level we'd like to expose newlist(), however 
we're waiting for list-strategies because it exposes an issue.  How do you pre-
allocate a list when you don't know what type it'll have?  The proposed solution 
is for newlist() to create an empty list with a PreallocateStrategy, this 
strategy promotes as normal to a specialized strategy, but uses 
rlib.objectmodule.newlist to preallocate tehe list.
