This is the response I got from our Xi18n experts on the Xim deadlock issue.

Hi Alan,

As Egbert commented, we cannot predict which Xlib functions are called from
XFilterEvent(). It's up to XIM implementation, under XI18N pluggable
interface.

In our implementation, we don't LockDisplay()/UnlockDisplay() in
XFilterEvent(),
since XFilterEvent() itself does not issue any requests to Xserver, hence no
needs to lock the display connection.

The bug is #4041914. As you see the bugid, we've done so almost 8 or 9
years on Solaris.

Can we suggest this as an alternative solution?

Regards,
Toshi
