"Before the specified function is executed, the value of func is set
to SIG_DFL. The next interrupt signal is treated as described for
SIG_DFL, unless an intervening call to signal specifies otherwise.
This feature lets you reset signals in the called function."

That's good enough (well not really *good*, but *enough*) to know
how to implement signal handling on missing-sigaction platforms.
