Heap exhausted on SBCL 2.4.5 Windows 10 x64, --dynamic-space-size 4096 is required

I coudn't load 3d-math on SBCL 2.4.5 running on a Windows 10 x64 machine with 16gb RAM unless I specified the command-line option --dynamic-space-size 4096. Previously I tried with 1024 and 2048 values.

Welcome to LDB, a low-level debugger for the Lisp runtime environment.
(GC in progress, oldspace=0, newspace=1)

Further loads are OK with the 1024mb default value, but that was a scary error that was hidden in the *inferior-lisp* buffer that SLIME didn't even report it.

Given that this library will most likely be used in a gamedev context, a more beginner user might be confused and give up doing gamedev in CL altogether.

Perhaps it's worth a mention in the documentation to warn Windows users about this issue and recomend --dynamic-space-size 4096?
