Description of problem:
After installing 2.14.89025, I was seeing lots of weird issues - programs trying to talk to pulseaudio would hang, firefox was wedged and flickering the X cursor between 2 different cursors, some other weird stuff.

Caught this in gdb of /usr/bin/pidgin hung during startup:

(gdb) c
Continuing.

Reverting to 2.14.90-23 and everything started working normally again -
pidgin, pulseaudio, firefox, etc.

Am willing to add instrumentation and re-test if somebody tells me what
they want tried.

Version-Release number of selected component (if applicable):
glibc-2.14.90-25.fc17

I had similar weird behaviors of applications in F16 (x86_64) after I
installed glibc-2.14.90-24.fc16.3. I googled and found (in Bug#651899 in
Debian) my problem might be related to glibc-rh552960.patch had been
introduced in 2.14.90-24.fc16.x. I locally build glibc-2.14.90-24.fc16.3
without the patch then everything have been working fine for two days. I
found the patch has been merged into glibc-2.14.90-25.fc17 tarball.

Got around to testing 2.14.90-26, which contained this:

  - Revert "fix" to pthread_cond_wait (#769421)

and it does appear to be working correctly on my box again.  Thanks..

Should be fixed by either 2.15-1.fc17 or 2.14.90-26.fc17 (both revert
the problematical pthread_cond_wait patch).

Title:
  audio unreliable with eglibc 2.15

Status in eglibc package in Ubuntu:
  Fix Released
Status in eglibc source package in Precise:
  Fix Released
Status in eglibc package in Fedora:
  Fix Released

Bug description:
  Audio is completely unreliable after upgrade to eglibc 2.15.

  - Google+ hangouts, which use the google-talkplugin package from http://dl.google.com/linux/talkplugin/deb/, initially have audio working, but within a minute or so the audio cuts out (in both directions).  This plugin uses pulseaudio via dlopen() of libpulse.so.0.
  - Skype, from the oneiric partner archive, exhibits similar behavior: audio is bidirectional when the call is established, then after a minute or so the input cuts out (despite pulseaudio's volume meter showing that audio is still being picked up from the mic)
  - Quodlibet (pulse-enabled media app implemented in python) plays music fine until it suddenly stops after a random period of time.  In my latest test, the current track has stopped at 4:59 into the song.  The UI still responds fine and if I select a different song to play, playback resumes.

  The G+ regression has been reported by several other people on IRC.
