// The test will fault with SIGFPE (ErrorHandlerTest=15) and then, during error handling,

|
// three pieces of reattempt logic are tested:
|
|
// * First a step will fault with SIGSEGV. And then reattempts the step twice. With the first
|
|
// reattempt succeeding. And the second reattempt being skipped.
|
|
// * Second a step will timeout, followed by a reattempt, the reattempt will be skipped.
|
|
// * Third a step will use almost all stack space and then fault with SIGSEGV. After this the
|
|
// proceeding reattempt steps will be skipped because of low stack headroom.
