split from issue #98 focusing here on unknown syscalls in net_unittests URLRequestTestHTTP.ProxyTunnelRedirectTest

/usr/bin/time ~/drmemory/git/build_drmemory/bin/drmemory.exe -batch -debug -dr c:/src/dr/git/exports -- ./net_unittests.exe --gtest_filter="URLRequestTestHTTP.ProxyTunnelRedirectTest"

should set mc.pc for syscall events so can get top frame!
=> DRi#442
then we have:
