+=item EIO_STACKSIZE
+
+This symbol governs the stack size for each eio thread. Libeio itself
+was written to use very little stackspace, but when using C<EIO_CUSTOM>
+requests, you might want to increase this.
+
+If this symbol is undefined (the default) then libeio will use its default
+stack size (C<sizeof (long) * 4096> currently).  If it is defined, but
+C<0>, then the default operating system stack size will be used. In all
+other cases, the value must be an expression that evaluates to the desired
+stack size.
