Mistake on my part - I thought you were using malloc and free.

You said the assert gets hit.  The one on line queue.c:1224 guards 
against the use of a mutex in an interrupt and the one in port.c against 
a non-interrupt safe function being called from an interrupt - so if a 
mutex is being used in an interrupt, the deferred handler bit of my last 
email would still hold true.
