[julia-users] IO writing to a shell command

[eric l]

So here is the code

function shllinout(some::ASCIIString)
rd,wr = redirect_stdout()
open (`sed 's/666//g'`,"w",STDOUT) do iob
println (iob,some)
end
    eof(rd)
    close(rd)
outoff = readall (rd)
redirect_stdout (STDOUT)
return outoff
end

if  sizeof(some) < ~50000  fct()  works and return what I am expecting

if the variable some is more than 100KB the code hang in the println().

I tried reducing the size of the write to iob and flushing regularly but no 
success!

So my question is is there some kind of limitation  on the size that can be 
written to a shell cmd? 

Thxs,

-Eric
