[sudo-users] Strange sudo hang in AIX

Hello there,

I noticed some (rare) hangs with sudo 1.7.9p1 on AIX 6.1. Those hangs
did not happen with 1.7.8p1.
It seems only to happen when sudo is used to run scripts as non-root users.
sudo hangs quite early, there is no syslog or sudo log entry yet. The
sudo process still belongs to the calling user.
When use truss to attach to the hanging sudo, I can see:
kopen("", O_RDONLY)             (sleeping...)

Because it happens very rare, I could not trace more.

Anybody seen this?
