This happens sometimes as the result of using the debugger for  
writing code.
I must confess that I do not know either how to reproduce at will nor  
how to fix it.

I use this dirty trick to circumvent this issue : in the process  
monitor, select the process
that is blocked, and debug it. In the debugger, send #signal to the  
"mutex" instance variable
of the WAProcessMonitor object, then resume the process using the  
"Run" button.

This should be enough in most cases.

Bon courage,
