/* initapc: tests having DllMain of a statically-linked dll send an APC
 * (thus the APC is prior to the image entry point)
 *
 * must be run w/ AppInit injection, else the APC will be prior to DR taking over
 *
 * expect:
 * w/ -native_exec_syscalls:
 *   *** re-taking-over @INTERCEPT_SYSCALL after losing control ***
 * w/ -no_native_exec_syscalls:
 *   *** re-taking-over @INTERCEPT_EARLY_ASYNCH after losing control ***
 * and, of course, to have no .C violations from bottoming out
 *
 * FIXME: add mechanism to get info from core w/o getting start/stop and
 * w/o sending to eventlog since don't want customers to get even if
 * ask for info events!
 * Right now, since can't do DRview on test that completes right away,
 * and aren't getting info from core, this test will pass even if it runs
 * natively.
