Extracellular signal-regulated kinase (ERK) signaling pathway is a critical signaling pathway that transduce the intracellular signal.

Using this data, a process can terminate itself after finishing the execution of a critical part of the code (if started) as long as it gets a SIGTERM signal in the middle.

If the underlying function is in the middle of a critical section and a signal is generated and handled, this can cause the function to be non-reentrant.
