	If this is taking more than a minute, suspect the "45 second tiumeout"
	feature of the MS client.  

	If the transmission is suffering from problems, and goes into
	heavy retransmits, it cxan take more that the 45 second maximum
	time allowed between smb ACKs by ms clients. In the case of
	"raw" transfers, this **could** mean that any file that takes 
	more than 45 seconds to transmit will time out.

	That Would Be Bad (:-))

	As a **pure experiment**, see if "read raw = no" causes the
	problem to go away.  If it does, suspect an underlying problem
	triggering the timeout and start checking hardware.
