Hmm, wow, seems to be true - I'll have to investigate this better.

Yep, seems to be the same thing.

Hmm, I couldn't reproduce this. There's one known unresolved issues with
some kernel+glibc combinations that caused segfaults (see ecasound/BUGS).
You could try with "LD_ASSUME_KERNEL=2.2.5 ecasound -c" and see if it
helps.

Very true. There used to be some technical limitations, which lead to
the statement in the docs, but nowadays the object names need no longer be
unique. I'll change the docs to match current status..
