Thanks to some suggestions on the Wine forums, I was finally able to pinpoint a
resolution for this problem.  Turns out that by disabling the 'fidelity'
setting (setting it to '0' (zero)) in the game's configuration file fixes this
whole problem (the game plays as I had expected it to and the
'err:ntdll:RtlpWaitForCriticalSection' disappears)  I played the game for a
little while after it loaded and in about a 20 minute time frame the error did
not appear at all.

As far as I can tell, the only thing turning 'fidelity' off does is disable
terrain damage.  I have no idea what else I could look at to help pinpoint a
more specific cause for this error to have occurred, but I can say that the
other individual who was originally able to play this game well (and who has an
identical Wine installation/Platform) had this function enabled (set to '2'). 
That individual's computer has the same nVidia drivers as I do, but a newer
card, so I wonder if this is a hardware thing?  If there is anything else I can
do to help test this, please let me know as I wouldn't mind spending more time
on this to figure out the root cause.
