peterhuene opened PR #3245 from add-paged-init-setting to main:

This commit adds a paged_memory_initialization setting to Config.

The setting controls whether or not an attempt is made to organize data
segments into Wasm pages during compilation.

When used in conjunction with the uffd feature on Linux, Wasmtime can
completely skip initializing linear memories and instead initialize any pages
that are accessed for the first time during Wasm execution.

The default here might be good to be based on uffd as a feature?
