OK, here's the result of some investigations:
o On lilith (RH-7.3, gcc-2.96, glibc-2.2.5-43, 2.4.20 kernel) *no*
zombies are generated for the conformance tests.
o On quisquiliae (RH-7.3, gcc-3.2.1, glibc-2.2.5-43, 2.6.0-test8
kernel) a single zombie is created, which happens when the kernel
DLL tests are run.
o Copying the whole lilith-compiled wine tree across to quisquiliae and
re-running zombtest, I get a zombie.
Looks suspiciously like the 2.6.0-test8 kernel is to blame. To confirm
this, I rebooted quisquiliae using a 2.4.20-kernel. Guess what? No

Not that much more. Originally, when running the full gamut of
conformance tests on my laptop (which is running 2.6.0-test9), six zombies
orphan processes were created.
One of these zombies was created when running the kernel DLL tests (the
one that is created when running 2.6.0-test8). I tracked the problem down
to tests/process.c line 967:
ContinueDebugEvent(de.dwProcessId, de.dwThreadId, DBG_CONTINUE);
