 clang is currently waiting on a child process to terminate

 and it looks like that process is xcrun:

 {{{

 }}}

 Can you take a sysdiagnose focused on xcrun instead of just the spindump
 and file a radar with it at http://bugreport.apple.com by doing:

 {{{
 $ sudo sysdiagnose -q 11027
 }}}

 After that, I suggest you just kill the process and reboot to get to a
 fresh state.
