15 /* IDL sizes - likely should be even bigger
16 * limiting factors: sizeof(ID), thread stack size
18 * Note: the -2 stuff is intended to reduce the size
19 * just enough to avoiding internal (to malloc) allocation
20 * of overly large blocks to provide the requested size.
21 * The stuff needs to be thought out better, doesn't deal
22 * well with mixed stack/malloc allocation of IDLs.
