Hi, Weldon:
Which file includes signalProtectMain() or gpProtectedMain ? :)

It looks like hysignal.c is using the right monitor enter/exit(). That

the one
from drlvm/trunk/build/win_ia32_msvc_debug/deploy/jre/bin/hythr.dll
However, a bunch of functions in classlib's hysignal.c have an incoming
argument of "HyPortLibrary *portlib". The portlib variable can either
point
to the original classlib portlib C struct. Or it can point to PORTLIB
which
is a C struct with all the entries nulled out (more on this later.)
I think the next question to ask is what hysignal.c does with
the "HyPortLibrary *portlib" argument. If anyone knows, please tell us.
Otherwise I will keep digging.
From stepping through DRLVM bootup, it looks like classlib's portlib is
_dropped_ in signalProtectMain(). Then launcher gpProtectedMain calls
invocation(PORTLIB,...) where PORTLIB is a nulled out HyPortLibrary C
struct. We need to put comments in the code describing the switch from
classlib's portlib to drlvm's nulled out version.
