Dear Miguel:
Indeed, data is not made available to the pipe; though it should be there,
because od prints lines as soon as they're available. I tried "readall",
but it also blocks. I should have added that I tested this with the latest,
0.4 release from github.
I also tried just reading one character, with "read(so,UInt8)", and this
also blocks.
I notice that you are the author of the gnuplot package "Gaston"; so you
are certainly familiar with the issue. Looking at Gaston's code, I see that
you directly called :popen from the C library. Is there a reason not to use
the higher-level interface of Julia?
I got more crashes by feeding large amounts of data to a pipe:
julia> (so,si,pr) = readandwrite(`od`);
julia> write(si,repeat("test\n",100000));
^CERROR: InterruptException:Assertion failed: (req->handle == stream),
