I don't think GLIBC_IFUNC or tunables are appropriate at this stage - 
anything involving new environment variables requires very careful 
consideration (of what APIs we want to support for users, of possible 
security issues, etc.) that we simply don't have time to do properly now.  
Because of the risk of architecture-specific issues that would invalidate 
testing already underway, I don't think the *fallocate* consolidations are 
appropriate now either.  I also think the pretty-printers are too big a 
change to include at this point.
