[Twisted-Python] txmongo vs. pymongo + callInThread

[Clayton Daley]

I (OP) was looking into these libraries/options as part of a side project
that's been delayed by real work.  I'm also relegating Mongo to a caching
layer after stumbling upon Sarah Mei's "Why You Should Never Use MongoDB"
and realizing I was going to have the exact same problems.
