I did fix this on 1.8.6: r27999

./configure --enable-pthread
# time ./ruby -ve '1_000_000.times { x = 2 ** 256 }'
ruby 1.8.6 (2010-06-12 patchlevel 415) [x86_64-linux]

real    0m3.006s
user    0m2.880s
sys     0m0.128s

./configure --enable-pthread --disable-ucontext
# time ./ruby -ve '1_000_000.times { x = 2 ** 256 }'
ruby 1.8.6 (2010-06-12 patchlevel 415) [x86_64-linux]
