If you need to shave off some kilobytes of code at the expense of some
speed, define this symbol to 1. Currently only used for gcc to override
some inlining decisions, saves roughly 30% codesize of amd64.
ev_child watchers use a small hash table to distribute workload by
+pid. The default size is 16 (or 1 with EV_MINIMAL), usually more
+than enough. If you need to manage thousands of children you might want to
+increase this value.
