 Ok - I've tried it out...
 
 I move the initialization of rep->r_mrep to be before the
tryagain: label, just as the other initializations were...

 Unfortunately; I still experience the hang...

 This problem seems to be  particular to readdir() - I'm wondering if 
readdir() is somehow doing an soreceive() without going through nfs_reply();
i.e. avoiding the nfs_rcvlock() somehow...
