// QEMU by default allocates (and commits) 1GB memory on Windows, and multiple Unicorn instances will result in OOM error easily.
// Unfortunately, Windows doesn't have a similar demand paging feature like mmap(), therefore a workaround is to use tcg regions mechanism.
// Note most Unicorn hacks (and even QEMU!) relies on the assumption that the translation memory won't run out and thus it might result
// in some unexpected errors. If that is case, define to align with QEMU and Unicorn <= 2.0.1 behavior.
