Browse source 
Applications may want to fine-tune the stack size of the fiber that's
used to make callbacks into the application.

Size of the receiving fiber stack. This is the context from
which all event callbacks to the application occur. The
default value is sufficient for basic operation, but if the
application needs to do advanced things in its callbacks that
require extra stack space, this value can be increased to
accomodate for that.
