The target will be removed when all packages not supporting 3.8 are
removed, so the exact time depends on what package will remain
in ::gentoo at May 1st.

Ideally, all packages will be ported by then and the only packages to
mask will be backports.  For these, I use the shorter 14 day period. 
However, if we have to remove some real packages I'll use 30 days
instead.
