Comment (by pdimov):

 I'm pretty sure that it can be fixed in principle using ldrex/strex; not
 only that, but it should be possible to implement sp_counted_base for
 armv6 using these, without resorting to a spinlock. However, I have
 neither the necessary experience with ARM assembly nor the resources to
 test the code.
