My report, some are the same than Esteban, as we work a lot together :D

### Last week:

- (Pair Programming with Esteban) Modifying the TFFI callbacks to
include information about the Smalltalk block in the plugin data
structure. This improves the debugging experience and the detection of
errors when a Callback in the image side is garbage collected.

- (Pair Programming with Esteban) Compiling the Queue based
ThreaddedFFI plugin to use the latest libffi version. This is required
to build in Catalina.

- (Pair Programming with Esteban) Adding synchronization code to
correctly interrupt the AIO waiting idle loop. This is still work in
progress as we have to test more scenarios. This modification allows
us to extend enormously the idle time of the relinquish processor
primitive without losing events nor delays.
