OK. This is the beast:
test cache-6.2 {eval ttl} -body {
ns_cache_eval -ttl 1 -- c1 k1 {return a}
after 1500
ns_cache_eval c1 k1 {return b}
} -cleanup {
ns_cache_flush c1
} -result b
It immediately results in the series of
invalid writes and reads. I will have to
isolate this in detail but here is the
breakdown of Purify:
