/tg/station13 /atom/movable Pool:
---------------------------------
By RemieRichards
Creation/Deletion is laggy, so let's reduce reuse and recycle!
Locked to /atom/movable and it's subtypes due to Loc being a const var on /atom
but being read&write on /movable due to how they... move.

//Goes into the pool
