[Ken Raeburn]

branch: scratch/raeburn-startup
commit 4c8f07e389f39ba0c03e698f707997232b961076
Author: Ken Raeburn <address@hidden>
Commit: Ken Raeburn <address@hidden>

    Increase gc-cons-threshold.
    
    The large "progn" block in dumped.elc greatly exceeds the old default
    GC threshold.  Garbage collection during startup becomes a non-trivial
    part of startup time.  (Less than 10% in my testing, but that's not
    nothing.)
    
    This is NOT a good long-term solution, at least by itself.
    
    * src/alloc.c (GC_DEFAULT_THRESHOLD): Increase to 3 million words.
