the last snapshot make no difference on winXP.

As people on Vista and W7/64 were reporting a

while on XP, starting from 2011-03-09 snapshot,  I have only the

I start to feel that they are 2 different problems that just arise from
the same plot operation in octave.

my strace shown

[main] octave-3.4.0 3764 fhandler_fifo::raw_read: returning -1, mode
2, Win32 error 997

I looked in the source of fhandler_fifo.cc but I see no special
handling of ERROR_IO_PENDING
that instead I see on other fhandler source files.
Could be this the problem ?
