   The name "mtsafe-malloc" itself is a bit of a giveaway.  If it's just    
   malloc() and free() then I'm not concerned.  I already use thread-safe    
   versions of those in TCPIP32.DLL, and always have done.  I was concerned    
   that you were talking about the getXbyY functions or some such.    
   Applications programmers thinking that those are thread-safe is    
   erroneous on more than just OS/2.
