Nothing netbsd-specific here.  If the delay between ESC and O exceeds
certain threshold (see keypad(3), search for ESCDELAY) ESC gets
interpreted as plain ESC (it's not "lost" as you hypothesize).  That
gets you into command mode, then O adds a new line and switches to
insert mode and the next char is then inserted.
