I have seen this tight loop as well, it is something new. However, I
tried to debug it by turning up the venus logging level and this somehow
stopped the tight looping.
But, when mgrpents.next is a NULL pointer, the following dereferences
should have at least triggered a segfault. Maybe the -O2 optimization
got in the way of reliably getting the variables contents?
! mgrpent *m = list_entry(p, mgrpent, volhandle);
! p = m->volhandle.next;
