.Random.seed saved in .RData

Is it intentional that the .Random.seed is saved in .RData?  If people 
run multiple sessions from the same directory they will get the same 
intial seed setting, which seems a bit dangerous. I don't often save my 
session nor run two sessions in the same directory, so I have never run 
it this, but there was a question on r-help where it may have been an issue.
