Indeed, thanks!  It seems I am using the default one (since I do not
specify a different one) and even I confirm this:

(WACache allInstances collect: [ :each | each reapingStrategy class ])
asSet -> a Set(WAAccessIntervalReapingStrategy)

And that class ends up using "WAAccessIntervalReapingStrategyConfiguration
instance" which defines:

describeOn: config
(config integer: #cacheReapInterval)
comment: 'The number of cache stores that are allowed before expired
objects are reaped from the cache.';
default: 10

And still, at the very beginning of this email I showed how my sessions
were not unregistered even if I had more than 10 instances around (I had 13
if I remember correctly).

mmmmm getting this code:

WACache allInstances collect: [ :each | each reapingStrategy instVarNamed:
'count' ] -> #(0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 7 2 5 0 0)

tells me that maybe I am misunderstanding the #cacheReapInterval. So maybe
it is not 10 sessions... but that each cache (assume one per session and
one per app) would be cleared only after something was stored there at
least 10 times???  mmmmmm

mmmm more confused than before...
