That's the reason, why I just sent the first part, where the initialization
of all the pipes and forked processes can be seen and the last part, when
scp is shutting down the processes again. I think the middle part,
observing scp looking into the private keys and sending the file, is quite
useless for this problem.

Yeah, understand that.

Since I call from Java always "strace -o /tmp/scp.strace scp" I don't have
the problem also. It's slow, but works. Too weird :(
At least I could reproduce it without Java also. FWIW.

As said, I'll take any further action to isolate it. Would you expect a
difference using the current snapshot?
