Details:

Some systems need special handling to create executable code segments. For
instance, GNU/Linux on Alpha, and Fedora Core 4 on x86. This patch use mmap
to allocate pages of executable memory and set the EXEC flag. However, mmap
allocates pages even to page_size (usually 4096 bytes) even for very small
blocks of data. We use a memory stack to manage blocks of executable memory.
