I am just building safe version.  Testsuite run took 235 minutes
compared to 18 minutues for safety 1 version.  While testsuite
probably is different than normal workload, it clearly shows
that runtime speed is even more affected than build time.  Also,
IIRC one safe version I tested failed a few tests runnning out
of stack space: safe version had tail recursion elimination
disabled (but I do not see this probem in current build).
