unknown windows error 64

[Shaffer, Kenneth]

I'm having a problem with cp returning "Permission denied". I managed to
strace it and found that after a whole lot of successful block
read/writes, an unknown windows error 64 shows up. A snippet of the trace
follows.

   79 42539116 [main] cp 1324 readv: 1024 = readv (3, 0x22D590, 1), errno
