Don't add each line one-by-one.  Concatenate all the lines into one very long
string (yes, there should be embedded newline characters) and then set the
XmNvalue to that string.  Just to nit-pick: if all you're setting is XmNvalue,
use XmTextSetString instead to avoid the Set-Values method and having to go
thru Xt.

Also, since you're using SCO UNIX, don't forget to compile with -lmalloc
or performance will always be sluggish.
