   Reproduced this again today, but with an instrumented external() function in   
   xtrn.cpp. It logged this before apparently hanging:

   /sbbs/exec/sbbsecho -les!y   
   ```   
   Lines 1827 - 1830 are these in that (modified version of) xtrn.cpp:   
   ```   
           lprintf(LOG_DEBUG, "%s %d %s", __FILE__, __LINE__, cmdline);   
           if(mode&EX_BG)  /* background execution, detach child */   
           {   
               lprintf(LOG_DEBUG, "%s %d %s", __FILE__, __LINE__, cmdline);   
               lprintf(LOG_INFO,"Detaching external process");   
               if(daemon(TRUE,FALSE) != 0)   
                   lprintf(LOG_ERR, "!ERROR %d (%s) daemonizing: %s", errno,   
   strerror(errno), argv[0]);   
           }   
   ```   
      
   So it appears to successfully log the last DEBUG line there, but not the   
   "Detaching external process" line.
