[kepler-dev] Sleep actor sleeping more than it needs to

[Christopher Brooks]

Hi Xiaowen,
   If you, or any other kepler developer, wants access to the devel
version of Ptolemy II, please go to 
http://chess.eecs.berkeley.edu/ptexternal/
and request an account.

It is much easier for me to create read only access accounts
than it is to create read/write accounts, so if possible, please start
with a read only account.

    Hi Edward,
    
    
    Thank you for the quick reply.
    
    I tried the actor you sent, but the workflow exhibited the same 
    behavior as before.  Actually, I realized that if the Sleep actor does 
    receive a token, it sleeps twice as long, and if it doesn't, it appears 
    to sleep once.
    
    Perhaps the fix was somewhere in the Ptolemy engine since the new actor 
    behaved the same as before in 4.0.1.
    
    I will now await very eagerly the next release of Ptolemy :)
    
    
    Thanks,
    Xiaowen
