performance/write-behind: guarantee non-overlapping concurrent writesv3.4.0alpha2
Maintain a list of writes (either written behind or SYNC) which are
currently "in progress" (i.e, STACK_WIND'ed towards server) and hold
off any new STACK_WIND of write (either written behind or SYNC) which
overlaps with any of the "in progress" writes.
This is a guarantee which AFR's eager-lock depends upon (though not
strictly a write-behind requirement)
