In the IUT, we have the following restriction.
If a multi-threaded process forks after creating one or more
threads, the child process cannot be multi-threaded (i.e it
cannot create any threads).
The VSTH test suite driver seems to be relying on the above behavior
to work correctly. However it is not stated in the standard that this
is a required behavior. Several tests fail with the message "UNRESOLVED"
Is the test suite driver correct in expecting this behavior to be
supported ?
Following is the list of tests that fail for this reason
