/**
* A UniConfGen that counts all "potentially synchronous" (ie. slow)
* operations, so you'll know for sure if you're calling UniConf synchronous
* operations when you shouldn't be. Hint: wrapping this one in a
* UniCacheGen is supposed to cut slow operations to a bare minimum, so a
* good test is to try a moniker like this:
*
* cache:slow:tcp:localhost
*
* ...and see if everything still works but there are no slow operations.
*
* (A previous version of this used to actually make things slow by doing
* a deliberate sleep() on synchronous operations, but that wasn't really
* needed. Now it just logs them instead.)
