 * The rate at which FreeBSD can generate callouts (kind of timeout mechanism).
 * For FreeBSD 8 this is typically 1000 times per second (100 for ARM).
 * This value is defined in a file called subr_param.c
 *
 * WHile Haiku can have a much higher granularity, it is not a good idea to have
 * this since FreeBSD tries to do certain tasks based on ticks, for instance
 * autonegotiation and wlan scanning.
 * Suffixing LL prevents integer overflows during calculations.
 * as it defines a long long constant.*/
