# Cliphist allows storng up to 5 MB per item entries, with 10 entries
# limit, this means 50 MB. Annoyingly, it seems to load all entries
# even when it's just writing a single new one (during `cliphist store`), 
# so we need to account for this. See: 
# https://github.com/sentriz/cliphist/issues/155 to understand
#
# If the above issue gets addressed, these limits can likely be lowered.

# Because of the issue above, significantly increase the likelihood of 
# this process getting terminated during OOM I don't really care that
# much about a clipboard manager staying up anyways.
