Just like when you are in line at a ticket window. Your kid comes up and say we need one more ticket. You cannot do anything about it until it is "your turn".

And "jiffies" resolution may or may not help in a single CPU box. The process still cannot process a signal until it is the current running process.

NAME
abort() - generate a software abort fault SYNOPSIS
DESCRIPTION
first closes all open files, streams, directory streams, and message catalogue descriptors, if possible, then causes the signal to be sent to the calling process. This may cause a core dump to be generated (see signal(2)). If the signal is caught, the handling function is executed. If the handling function returns, the action for is then reset to and the sig- nal is sent again to the process to ensure that it terminates. RETURN VALUE
does not return. ERRORS
No errors are defined. APPLICATION USAGE
is not intended to be caught. DIAGNOSTICS
If is neither caught nor ignored, and the current directory is writable, a core dump is produced and the message is written by the shell. SEE ALSO
adb(1), exit(2), kill(2), signal(2), signal(5), thread_safety(5). STANDARDS CONFORMANCE
