 <paraphrase origin=3D"aRts author">
 Indeed, aRts is linked with pthreads, which causes issues becuz some
 parts of aRts aren't thread-safe (and thus cannot use reentrant forms of
 libc functions).  Noatun is also not thread-safe.  The fact that
 pthreads is implemented in user-space makes it impossible to change the
 reference for the appropriate syscalls.  At least this is true for 4.x.
 Hopefully 5.x will put pthreads in the kernel.
 
 This problem will be revisited for KDE 2.2, where the author of aRts is
 going to offer non-threadsafe versions for the libraries in aRts which
 are written in a threadsafe manner.

 I may not remember something above correctly, but it makes sense to me.
