I attached using strace to the running Emacs process when this happened and
captured the log.

Please let me know if any other information is required.

1) It's better to attach gdb and try to obtain a backtrace, especially when
Emacs sits in CPU-eating loops.

2) If CPU-eating loop involves I/O (read/write/sendmsg/recvmsg/select/etc.),
try to understand how the relevant fds are used, by looking under
/proc/[Emacs PID]/fd directory. (In your log, the most important is fd 4;
probably this is an X socket).
