I checked this with Mathematica 4.1 for MacOS X and discovered something 
rather curious. If I use the Front End to try to perform this 
computation the kernel quits. However, if I run the kernel without the 
FrontEnd I get:


In[1]:= a=Log[Log[x*Exp[x*Exp[x]] + 1]] - Exp[Exp[1/x]]*Log[x]

             1/x                         x
            E                           E  x
Out[1]= -(E     Log[x]) + Log[Log[1 + E     x]]

In[2]:= Limit[a,x->Infinity]

Out[2]= Infinity
