Using a hash-table context property

[Dan Eble]

After adding a property to define-context-properties.scm and initializing it in 
Score context in engraver-init.ly <http://engraver-init.ly/> to a hash table 
created with alist->hash-table, my engraver is able to get the table and use 
it.  My problem is that the entries the engraver adds persist to the next 
score!  I was expecting the next score to start again with the default table 
given in engraver-init.ly <http://engraver-init.ly/>.  What am I missing?

Thanks,
