// Create a new java process for the TestPsig Java/JNI test.
// We run the VM in interpreted mode, because the JIT might mark
// a Java method as not-entrant, which means turning the first instruction
// into an illegal one. Calling such a method after establishing
// the new SIGILL signal handler with TestPosixSig.changeSigActionFor(4)
// below, but before the JNI checker noted and reacted on this signal handler
// modification, the JVM may crash or hang in an endless loop, where the
// illegal instruction will be continously executed, raising SIGILL, and
// the signal handler will return to the illegal instruction again...
