elisp: customizable patience amount on racket startup
In this little notebook i'm using, racket takes its time to start. In fact, it can take more the previously slotted 10 seconds. Hence the new geiser-repl-startup-time variable.

+@subsubheading Racket startup time
+
+When starting Racket in little computers, Geiser might have to wait a
+bit more than it expects (which is ten seconds, or ten thousand
+milliseconds, by default). If you find that Geiser is giving up too
+quickly and complaining that no prompt was found, try to increase the
+value of @c{geiser-repl-startup-time} to, say, twenty seconds:
+
+@example
+(setq geiser-repl-startup-time 20000)
+@end example
+
+@noindent
+If you prefer, you can use the customize interface to, well, customise
+the above variable's value.
