Everything involving I/O that needs to be done on the main loop should
be done asynchronously. That's precisely why GLib-based libs have such
good support for async operations: To avoid blocking the GUI.
In particular for WebKitGTK, if the data you need to exchange between
the GUI process and WebExtension can be trivially formatted and
re-parsed (GVariant helps a lot with that), then consider using
If the data you need to load from the GUI process is large enough,
maybe consider registering a custom URI scheme handler using
webkit_web_context_register_uri_scheme(), then let WebKitGTK handle
getting the data to the WebProcess asynchronously for you.
If neither of those are a good fit, write an async protobuf wrapper
using a background thread, so that when it blocks, it doesn't block the
GUI as well.
Geary uses the first two of these approaches with WebKitGTK, and the
last approach for interacting asynchronously with SQLite, and they all
work quite well.
