POSIX 1003.1 wouldn't like this at all:
3.3.1.2, pg 73: "Conversely, when SIGCONT is generated for a process, all pending stop signals for that process shall be discarded." 3.3.1.2, 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.
