+    redirecting standard out to a file, the contents of which are returned; (iii) protect the child
+    process from [SIGQUIT].
+
+    We want to ihnibit [SIGQUIT] because the standard action of the JVM is to print a thread dump on
+    stdout, polluting the output we want to collect (and normally does not lead to process death).
+    To achieve this we need to do two things: (i) tell the JVM not to use signals, meaning it leaves
+    the default handler for [SIGQUIT] in place; (ii) uninstall the default handler for [SIGQUIT]
+    because now that the JVM doesn't touch it, it will lead to process death. *)
