I don't know (I have 2.1.5 now), but maybe there is a newer version of vi in
2.2.  Type :ver, and see it.  In 2.1.5, it's a very-very old 1.34 (from
'94) version in it, maybe in 2.2, it's a newer.  If I remember well, in
newer nvi's (1.7x ?), there is a new handling of the <ESC> timeout.
In 1.34, it's only :set timeout/:set notimeout, but it may changed.

Oopps!  I've found, that :set keytime=X may interested in you.
