 Summary: [C++] Add interface to turn stl_allocator into 
arrow::MemoryPool
 Key: ARROW-3610
 URL: https://issues.apache.org/jira/browse/ARROW-3610
 Project: Apache Arrow
  Issue Type: New Feature
  Components: C++
Reporter: Uwe L. Korn


We already support constructing an {{stl_allocator}} from a {{MemoryPool}}, we 
should also support the reverse conversion. As the STL allocator does not 
provide a resize, this will always reallocate, even if there is support for it.
