[Ns-developers] Tip: WAFCACHE

[Gustavo Carneiro]

I have to correct myself.

Unfortunately it seems this WAFCACHE feature has suboptimal stability, so
forget what I said :-(

Hopefully in some future waf version this feature will work more stable, but
for now it is better to just no use it.

Sorry for the noise.
