The original idea was that SharedQueue2 will replace SharedQueue. The 
problem is that this didn't happen and SharedQueue only understands #flush 
and #flushAllSuchThat:, so removing these methods will not enable us to 
do the switch. The reason why it didn't happen yet is probably 
performance. In the meantime Igor made some other queues which don't use 
any synchronization primitives, so they are a lot faster than both 
SharedQueue and SharedQueue2 for the basic operations. In theory Pharo 
uses one of those queues instead of SharedQueue in EventSensor (or it's 
replacement), though I'm not sure, since I didn't check it.
Anyway, SharedQueue is a hack, SharedQueue2 is clean(er), but slow(er).
