Yes, with --enable-single-host option Gambit runs about 1.5 to 2 times
faster. But on my x86_64 machine compilation with some not-so-good
versions of GCC (4.3.x) take about 10 Gigabytes of virtual memory in
peak and near 30 minutes. If target architecture is 32bit with small
amount of registers (x86, for instance), then --enable-single-host is
strongly recommended option.

PS:  For MIPS32 arch on Au1250 system compilation of Gambit took about 6
hours with --enable-single-host :)
