Question: rrdtool pipe interface - restore support?

Hi,

Does the rrdtool pipe interface somehow support an in-stream xml restore
command?

"dump" is  (mostly) working as expected, although one has to look for
the "OK" response line to find out where the xml ends, but this is not a
problem. "restore" however has the problem that it does not take input
over the pipe interface. Using "-" as XML input seems to *partly* work,
but fails with a parser error. Using /dev/stdin works when using the
pipe interface on the command line, but can't work when using the pipe
over a TCP connection....

Any ideas?

I admit that I am using a rather old version: 1.4.7...
