required ctx is valid in mem_isovermem().

2937. [bug] Worked around an apparent race condition in over memory conditions. Without this fix a DNS cache DB or ADB could incorrectly stay in an over memory state, effectively refusing further caching, which subsequently made a BIND 9 caching server unworkable. This fix prevents this problem from happening by polling the state of the memory context, rather than making a copy of the state, which appeared to cause a race. This is a "workaround" in that it doesn't solve the possible race per se, but several experiments proved this change solves the symptom. Also, the polling overhead hasn't been reported to be an issue. This bug should only affect a caching server that specifies a finite max-cache-size. It's also quite likely that the bug happens only when enabling threads, but it's not confirmed yet. [RT #21818]
