  # On Windows the engine finds the Dart snapshot data through symbols
  # that are statically linked into the executable. On other platforms this
  # data is obtained by a dynamic symbol lookup.
  # The current Windows platform uses static-link instead of dynamic lookups.
  # Because:
  #  1. The size of the executable on Windows is not as concerned as on mobile
  #     platforms.
  #  2. If it is a dynamic lookup method, you need to modify the properties of
  #     the memory page after the *.bin is dynamically loaded at runtime and
  #     mark it as executable. This is feasible (similar to V8 on Windows), but
  #     this increases the complexity of the implementation(These operations
  #     involve the use of some system file/memory privilege APIs and there is
  #     a risk of failure).
  #  3. In the executable can enjoy the advantages of the windows preload
  #     mechanism, speed up I/O.
