I found 2 issues:

1) Compile time almost doubled. Tested on vibe.d
    28 seconds - dmd 2.063 + updated snn.lib
    52 seconds - dmd 2.064 beta

2) Regression - After building vibe.d as a lib I was not able to 
link it with application. I get:

   Error 1: Previous Definition Different : 
_D12__entrypoint12__ModuleInfoZ

Both tested using command line -lib -g -debug -w -property -X 
-Xf"x.json" -Isource -deps="x.dep" -of"x.lib" -map "x.map"
