Kaz Wesley	b3ddc5e76f	LockedPool: avoid quadratic-time allocation ... Use separate maps for used/free chunks to avoid linear scan through alloced chunks for each alloc.	2016-11-02 16:52:56 -07:00
Kaz Wesley	0b59f80625	LockedPool: fix explosion for illegal-sized alloc ... Check for unreasonable alloc size in LockedPool rather than lancing through new Arenas until we improbably find one worthy of the quixotic request or the system can support no more Arenas.	2016-11-02 14:41:40 -07:00

Wladimir J. van der Laan	4536148b15	support: Add LockedPool ... Add a pool for locked memory chunks, replacing LockedPageManager. This is something I've been wanting to do for a long time. The current approach of locking objects where they happen to be on the stack or heap in-place causes a lot of mlock/munlock system call overhead, slowing down any handling of keys. Also locked memory is a limited resource on many operating systems (and using a lot of it bogs down the system), so the previous approach of locking every page that may contain any key information (but also other information) is wasteful.	2016-10-27 13:17:25 +02:00
