I disagree that this will be a bad steo for the reasons you gave.

  (1)  How many system calls are there?
  (2)  We're not on the critical path.

Is there any reason why this isn't an inline function?

namespace __gnu_cxx
{
    inline void
    write_message(const char* msg)
    {
       write(2, msg, strlen(msg));
    }

|  	  
|  	  dem = __cxa_demangle(name, 0, 0, &status);
|  
| -	  fprintf(stderr, "terminate called after throwing a `%s'\n", 
| -		  status == 0 ? dem : name);
| +	  errwrite("terminate called after throwing a `");
                   
          write_message("std::terminate called after uncaught expection '");

If we're going to be verbose, then please let's be explanatory.  Also,
it was agreed at some point that "`...'" is bad quoting.
