Console output from Wine 2.3

realMYST (as distributed by GoG) crashes near the end of the introductory
sequence, right before the book lands at the bottom of the screen.  If I abort
the introduction, I can start playing the game, which seems to work fine,
except that it crashes after a few minutes (usually, but not always, when I try
to save).  The console output gives a message about too many files open:

err:winediag:FILE_CreateFile Too many open files, ulimit -n probably needs to
be increased

I note that this is the same problem reported by Comment #10 of Bug 18975.  I
haven't tried increasing my maximum number of open file descriptors. It's
currently set to 1024, though I think it would be bizarre for the game to
require even that many.

Unfortunately, it is not possible for me to get a backtrace.  When I use
winedbg, the game slows to a crawl and it's impossible to do anything.
