So it's the same timeouts Andreas Løhre is also seeing.
I wonder whether there's a missing "volatile" or such.

These are basically expected, yes. In both receiver threads, the
message written to the upstream pipe gets the message length
prepended, and the write() calls for the message length are not
checked.
As I intend to combine these write calls with the subsequent packet
write itself (so the entire write() operation to the pipe is atomic),
I don't want to touch this now. I don't think this is related to the
problems you are seeing.

OK, there's a point in this warning. Instead of returning false, the
function should better throw an exception. However, it's for the
original JTAGICE ("mkI") only, so unrelated here.
I've fixed this in the source, anyway.
Too bad the warnings don't give us a hint about what might be the problem.
