bug#6237: 23.2; INSUFFICIENT RESOURCES writing file via CIFS

[Jack Holloway <forum2@sprucehead.com>]

Sorry for the gaffe -- this should be plain text.  Let me know if it's not.
---------------------
Saving a 32MB file to a CIFS path fails.  Examining Procmon
events shows a return status "INSUFFICIENT RESOURCES" on a WriteFile
with length 32MB.

Perhaps write-region should break down the write into a series
of blksize writes?

Here's the relevant backtrace:
Debugger entered--Lisp error: (error "IO error writing 
z:/Temp/test/tmp2092CxD: Invalid argument")
   write-region(nil nil "z:/Temp/test/tmp2092CxD" nil 
"z:/Temp/test/temp-write-once-032768" 
"z:/Temp/test/temp-write-once-032768" excl)
   byte-code("..." [dir tempname realname buffer-file-truename 
make-temp-name expand-file-name "tmp" write-region nil excl] 8)
   basic-save-buffer-2()
   basic-save-buffer-1()
   basic-save-buffer()
   save-buffer()
   write-file("z:/Temp/test/temp-write-once-032768")

This was running on Windows XP64 Professional SP2.  The drive "z:" is
mapped to a NAS running Samba.  This error doesn't occur
when writing to the host's internal NTFS, it does occur with other
CIFS targets.  copy-file doesn't have this problem.
