The nprocesses test is using the SIGPIPE signal to shutdown the spawned child applications. This is done in order to silence the shell message such as this one:
"nprocesses/test_nprocesses: line 79: 26458 Terminated" This mechanism is broken on systems where the SIGPIPE default handler is overriden (thus no application shutdown occurs) in the executing environment. This could lead to stale applications polluting the system and causing heratic behavior in subsequent tests. This commit add a loop and check that all the spawned applications have been successfully killed.
