IIUC no, since this window of time is very short and it's entirely
within adjust_markers_for_* functions.

Also note that adjust_after_replace and del_range_2 adjusts markers
first and overlays next, but replace_range and replace_range_2 adjusts
overlays first; moreover, both replace_range and replace_range_2
has comments which says that "markers first, overlays next" is the
correct order. This is pretty strange.
