This is a fine description but how does Mnesia determine whether to  
lock a table or a record?

 From my inspection of the sources it seems that a table lock is used  
for writes and record locks are used for certain types of reads.

Is this correct? Is a table lock always used for writing?

	Thanks, Joel
