By the way, your monitor.stp contains this bit:

   /* I don't know how to do this better, indexing envp
   if ($env->envp_idx > 0) printf("  %s\n", $env->envp[0]$)
   if ($env->envp_idx > 1) printf("  %s\n", $env->envp[1]$)
   [...]
   if ($env->envp_idx > 9) printf("  %s\n", $env->envp[9]$)
   if ($env->envp_idx > 10) printf("..... more\n")

More idiomatic would be as follows (stap version 0.9.9+):

   for (i=0; i<$env->envp_idx; i++) {
       printf("  %s\n", $env->envp[i]$)
   }
