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

[xiaowen]

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
