Minimal test case showing the bug.

If I hold a key for a long time on my keyboard I always expect the attached program to have interleaving "Down" and "Text" output. It sometimes work and sometimes it doesn't. The "Text" output (i.e. the TEXT_INPUT events) get lost. 

E.g. here a sample problematic output first I made a key repeat with key a that worked. Then a key repeat with key f but this one loses subsequent Text events:

> ./minc 
Down A
Text a
Down A
Text a
Down A
Text a
Down A
Text a
Down A
Text a
Down A
Text a
Down F
Text f

Hey Jorgen, any ideas?

Off the top of my head, maybe this is triggering the long-press IME composer that was introduced in 10.7 or 10.8. I'll take a look later.

Definitely seems related to IME - the multiple "text" events seem to only happens on keys that have the "long press" IME popup in other applications.
