I really appreciate the flexibility IBM demonstrates in the last sentence:

Be running with POSIX(ON) and have set the environment variables to signal
that you want to establish a nested enclave. You can use the __POSIX_SYSTEM
environment variable to cause a system() to establish a nested enclave
instead of performing a fork()/exec(). __POSIX_SYSTEM can be set to NO, No,
or no.

Yes - From my reading of the DOC, each TCB can have
a separate and independent LE ENCLAVE.  This has proven to be true and
works well.
