 Bash checks permission calling eaccess(2). The issue is that it returns
 success for root:
 
  19632 bash     CALL  eaccess(0x28417600,X_OK)
  19632 bash     NAMI  "/root/.cshrc"
  19632 bash     RET   eaccess 0
 
 sh's test has a workaround for this:
 
         case FILEX:
                 /* XXX work around eaccess(2) false positives for superuser */
                 if (eaccess(nm, X_OK) != 0)
                         return 0;
                 if (S_ISDIR(s.st_mode) || geteuid() != 0)
                         return 1;
  
 The eaccess(2) behaviour has been changed in CURRENT. See kern/125009 for
 details. I think this ticket can be set as a duplicate of kern/125009.
