Ok, two things:
Firstly - As demonstrated in the sample application that I attached with
the original post, I was using the combination of cache.ram with
cache.disk, as my default cache: cache.ram(key, lambda: cache.disk(...),
ttl)
Secondly, in the scenario where I create instance of CacheInRam, and
CacheOnDisk, and use them like so:
cache_ram = CacheInRam()
cache_disk = CacheOnDisk(ONE_CONSTANT_FOLDER)
cache_ram(key, lambda: cache_disk(key, lambda: ..., ttl), ttl)
In the second case, yes the instances are new ones per request ( but
this is a scenario I tried when testing my application independent of
web2py). Note that it goes to the disk everytime, and all the cache disk
instances are referring to the same cache folder. So, in this case,
whether it refers to the same cache folder or not, it basically is not
sharing the cache data ... is that what you meant? This is the reason
why I did not see any contention.
Whereas, in this second case, if I were to retain a singleton of
cache_disk, then I should be seeing the issue with cache.disk?

Ohh wait a minute I thought only cache disk was involved. If you
create new instances of CacheRam instead of using the one already
provided you are not using the cache at all as the new instances will
have an empty cache.
