[Reflectivity] change regarding announcement in Pharo7

Hi,

One questionable (but practical) thing that MetaLinks have is that they announce (MetalinkChanged) when they are installed or uninstalled.

This is nice for being able to show them in the UI (and e.g. the Watcher implemented with them).

But it is very very slow… so I now made it an option:

https://github.com/pharo-project/pharo/pull/1160

it is by default off, but can be turned on reflectively at any point.

e.g. the link of the execution counter now looks like this:

link := MetaLink new

metaObject: self;

selector: #increase;

optionAnnounce: true.

It has announcing enable so that the browser refreshes when it gets added or removed.

Hi,

Interesting.

What exactly is slow? The installation of a meta link? How slower is it?

Cheers,
Doru

yes, as the IDE updates. I is really slow, to the point i did not even benchmark.
(just running the tests feels extremely slow, in Pharo6 getting slower the more browsers are open)

And the tests do not even install many links.

We could get numbers by running all tests before and after the patch.
