Re: freeze due to interrupted futex system calls

[Richard Stallman]

    stopped (status 'S') and using 'strace -p' I get repeatedly the
    following trace:

      futex(0x407d9860, FUTEX_WAIT, 2, NULL)  = -1 EINTR (Interrupted system 
call)
      --- SIGIO (I/O possible) @ 0 (0) ---
      sigreturn()                             = ? (mask now [SEGV])

This sort of information isn't useful for debugging.

To get useful info, could you please start running under GDB all the
time, so you can make a C and Lisp backtraces using the `backtrace'
and `xbacktrace' commands?  See etc/DEBUG.
