xfmusic4 NPTL issue?

hi all-

i got a new laptop a week or two ago, and i built glibc with NPTL and 
TLS support, unlike on my main desktop machine.  i went and compiled and 
installed xfmusic4 on my laptop, and it's behaving strangely.  the GUI 
locks up most of the time when playing songs.  actually, xfmusic4-cli 
behaves similarly in that it pauses for long periods of time between 
updating the playback position display.  has anyone else seen this on an 
NPTL-enabled system?  to check, just run /lib/libc.so.6 from the 
commandline, and look in the list of "Available extensions".  one should 
read "Native POSIX Threads Library by Ulrich Drepper et al", and below 
that section you should (probably) see "Thread-local storage support 

i've added some printfs, and what i expected is happening - the main 
thread is taking a ridiculous amount of time to acquire the XfMusic 
object's stream mutex - even while the audio thread repeatedly aquires 
and drops it.  adding a g_thread_yield() call to the audio thread's main 
loop might alleviate this, but by no means do i see that as an 
acceptable solution.

so i'm interested in three types of scenarios:
1) if you ARE seeing this problem and you DO have an NPTL-enabled system
2) if you ARE NOT seeing this problem and you DO have an NPTL-enabled 
3) if you ARE seeing this problem and you DO NOT have an NPTL-enabled 

as you might guess, i only need replies if you fall into one of those 3 

thanks all.  now that i'm moved in and mostly settled in my new 
apartment, i'll be getting back to development on xfmusic4, and xfce in 
general, starting this weekend.
