DEC/Compaq/HP Tru64 has a flag to enable/disable overcommit. The major benefit seems to accrue to disk vendors with all the additional swap space needed. FreeBSD behaviour in the face of swap shortage is a regular and popular discussion topic. I suggest that a perusal of the archives will probably answer any questions. If anyone wishes to suggest a "solution" to FreeBSD's behaviour when there is a shortage of swap, please include patches.
