POSIX 1003.1 wouldn't like this at all:, pg 73:
"Conversely, when SIGCONT is generated for a process, all pending stop
signals for that process shall be discarded.", pg 76:
"While a process is stopped, any additional signals that are sent to
the process shall not be delivered until the process is continued

So no, SIGSTOP/SIGCONT can't nest.
