Just a heads-up for others who may not be aware of this - I was not
until today, until I began to look at my options table with ~250,000
entries in it (after 2 months!)...
WordPress does not garbage-collect transients unless you attempt to
access them. This means that if you use transients with unique keys, or
keys that are not expected to be used after a certain time (e.g. as
access tokens), then they may never be purged.
Here's a simple plugin to provide temporary relief until this is fixed
