|
||
|
|
// to set up (i.e. the ACME server would give up polling DNS or
|

|
|
// the client would timeout its polling). By separating Present()
|

// from Wait(), it allows the slow part of all solvers to begin

// up front, rather than waiting on each solver one at a time.

// to succeed assuming infinite time.
