Jarkko, did this turn out how you expected?

I think passing around a function pointer to *only* communicate 1 bit of
information is a _bit_ overkill here.

Simply replacing the bool with:

enum sgx_reclaim {
	SGX_NO_RECLAIM,
	SGX_DO_RECLAIM
};

would do the same thing.  Right?

Are you sure you want a function pointer for this?
