 I am a fan of running LTS releases, however 0.2.9.14 leaks memory
 continuously on relays serving as HSDIR for an apparently popular onion
 service and while also under attack.

 Daemon leaked 1GB in eight hours growing from 1.5GB VMRSS to 2.4GB VMRSS
 and was killed due to limited RAM.

 To remain viable 0.2.9 branch requires backports of 0.3.2.8-rc memory
 fixes, otherwise must be deprecated.

 Presently I am switching to 0.3.2.8-rc to see how the relay behaves the
 next time this happens.  Lately high-volume onion services come its way
 shortly after the HSDIR flag is assigned.

 see #24737 for some details
