* configure.ac: Added AC_ARG_ENABLE(time-check). By default, warning messages will now be printed for threads or commands that take longer than 5 seconds, but this configure argument can be used to disable the checks or change the threshold. * thread.h (thread_consumed_time): Declare new function to calculate elapsed microseconds. * thread.c (thread_consumed_time): Must be global not static so we can call it from lib/vty.c:vty_command. (thread_should_yield): Surround with `#if 0' to make clear that this function is not currently being used anywhere. (thread_call): If CONSUMED_TIME_CHECK is defined, print a CPU HOG warning message if the thread takes more than CONSUMED_TIME_CHECK microseconds. * vty.c (vty_command): If CONSUMED_TIME_CHECK is defined, print a CPU HOG warning message if the command takes more than CONSUMED_TIME_CHECK microseconds.
