Pd's symbol-table allows only one receiver per symbol. On top of this, 
pd_bind and pd_unbind implement a kind of splitter using a hidden 
[bindlist] object, which is only ever used internally, and only when 
there's more than one receiver per receive-symbol.

When you close several patches through that symbol, the message is handled 
a method in [bindlist], which terminates only when all receivers are 
finished handling the message.

When a canvas closes, it removes itself from the receivers list using 
pd_unbind. When the number of receivers goes from 2 to 1, pd_unbind 
deletes the [bindlist] object. At this point, [bindlist]'s method has not 
finished running, which is what causes the crash.
