| #### D.2.3.17 watchdog Procedure from library `general.lib` (see general_lib). Return: Result of cmd, if the result can be computed in i seconds. Otherwise the computation is interrupted after i seconds, the string "Killed" is returned and the global variable 'watchdog_interrupt' is defined. Note: * the current basering should not be watchdog_rneu, since watchdog_rneu will be killed * if there are variable names of the structure x(i) all polynomials have to be put into eval(...) in order to be interpreted correctly * a second Singular process is started by this procedure Example:
    LIB "general.lib";
    proc sleep(int s) {return(system("sh","sleep "+string(s)));}
    watchdog(1,"sleep(5)");
    ==> Killed
    watchdog(10,"sleep(5)");
    ==> 0
