Bug#708976: Prints "Cannot create thread" on startup

[Kevin Locke]

Package: libffado2
Version: 2.0.99+svn2171-2
Severity: normal

Dear Maintainer,

On my system, every program which links against libffado prints the
following message when the program runs:

Cannot create thread 1 Operation not permitted

This happens regardless of how the library is used.  For example,
running the following code will demonstrate the issue:

echo "int main(void) { return 0; }" | gcc -o dummy -lffado -xc -
./dummy

The error is being printed at src/debugmodule/debugmodule.cpp:404
because the debug client thread can not be created with SCHED_FIFO
scheduling priority.

Any way we can either avoid the error, avoid printing the error message
(if it's not serious), or make the error message a bit more useful for
users?

Thanks,
Kevin
