At one point this was a loop (el.prev = &el;). This outsmarted the
above behaviour. Unfortunately this trick doesn't work anymore with
Windows 2008, which irremediably gets into an endless loop, taking 100%
CPU. That's why we reverted to a normal SEH chain.
On the bright side, Windows' behaviour is covered by POSIX:
"If and when the function returns, if the value of sig was SIGFPE,
SIGILL, or SIGSEGV or any other implementation-defined value
corresponding to a computational exception, the behavior is undefined." */
