==name leak

==short-description

A tool for purposefully wasting memory.

==long-description

Sits in a loop allocating memory. This continues until either the specified amount of memory has been consumed, or an error occurs. The allocations are not done in the main application heap, rather the from a raw RChunk (the default), or via an RHeap (C<User::ChunkHeap()>) if the C<--heap> option is given. The command waits for a keypress before exiting and freeing the memory.

L<gobble|gobble>

==argument int amount optional

The target amount of memory to consume (in bytes). If not specified attempts to consumes all available memory.

==option bool v verbose

Display more detailed output.

==option int i increment-amount

The number of bytes to leak on each increment. If not specified and a target amount is specified, tries to allocate the entire target amount in one go. If not specified and a target amount isn't specified either, defaults to 4096 bytes. Note that unless C<--heap> is used, the increment amount must be a multiple of 4096 bytes.

==option uint r rate

The amount of time (in milliseconds) to wait between each increment. Defaults to zero (i.e. no wait).

==option bool H heap

Use a ChunkHeap to consume the memory rather than a straight RChunk.

==option bool t retry

If specified, when an allocation fails retry using a smaller increment amount.

==option bool l logging-allocator

If specified, install the logging allocator before starting to leak memory. Assumes the C<--heap> option.
