I've profiled with the latest changeset in the default
branch. Attached is a simple graph with the less time consuming
functions hidden and a full graph with everything. See [1] for help on
readings these graphs.

- I have no idea why tputtab is <spontaneous> according to gprof.
- The most time consuming function is tsetchar() which is normal since
it basically adds a glyph to the terminal internal representation.
- I don't understand why is really laggy.
