	If TEKKOTSU_SHM_STYLE is set to SYSV_SHM, SysV style shared memory will be used (shmget, shmctl, shmat, shmdt, ...) SysV style seems to stick around following a program crash, and can't be unlinked pre-emptively while still in use. Since it appears many systems also limit the number of shared memory regions (via a sysctl configuration), leaking regions following repeated crashes during development gets annoying.
#define	NO_SHM   3
	If TEKKOTSU_SHM_STYLE is set to NO_SHM, all shared memory operations become straight new/delete's; this restricts the program to using threads in a single process.
#define	TEKKOTSU_SHM_STYLE   NO_SHM
	Can be set to one of POSIX_SHM, SYSV_SHM, or NO_SHM.
