Context-#session

[Keith Hodges]

In trying to implement MagmaPersistency it turns out that the fact that 
PRContext holds a local cache to the current session may be a bit of a 
pain. Not only may there be a lot more stuff accidentally persisted 
through this reference, there may actually be objects that magma gurus 
say 'don't persist these if you know what is good for you'.

I cant see that this cache is widely used, so I wondered if anyone would 
object if it was removed

i.e. make this method lookup the current session the hard but not all 
that slow way (about 100 microseconds, on my oldish 700Mhz machine)

PRContext>>session

^ WACurrentSession value

any thoughts/opinions?
