Change Description

It appears that rodeos running on a certain k8s cluster is having trouble using mmap. This change:

  • Increases diagnostics to help narrow in on the problem
  • Strengthens the wasm mmap cache so it doesn't dispose (and later have to recreate) regions when other errors occur.
  • Preallocates wasm mmaps ahead of time
