When Emacs is non-responsive, there are always the same things to look at:
1 - is it fully unresponsive: i.e. does C-g break out of the hang?
2 - if C-g breaks out of it, what backtrace does it give, if you set
    Options -> Enter Debugger on Quit?
3 - If C-g doesn't help, run Emacs under a debugger and while it's frozen,
    interrupt the program from the debugger and check the backtrace (and do
    that repeatedly a few times, comparing the various backtraces you get,
    so as to determine at while level of the backtrace is the looping
    happening).
