Given a lock and a callable, invokes the callable under a lock in an exception-safe manner and returns its result (if any).

	// I wrote this little helper function while working on a disaster of a
	// codebase with little to no locking. One of my main goals was to make
	// it thread safe.
	//
	// I needed an easy to grab a lock, do some work (which could sometimes
	// throw an exception) and then release the lock, but I did not want to
	// have lock_guard objects littered in every part of the code.

0.31.2 announcement

	A new release of rippled - version 0.31.2 - is now available. This release:

	* Corrects a defect in the fee escalation algorithm that would cause network fees to
	escalate more rapidly than intended; additionally, the minimum local fee, as reported
	by validators, will no longer be adjusted upwards.
	* Gracefully handles ledger validations which do not include the optional LedgerSequence
	field. Earlier versions of rippled incorrectly assumed that the field would always be
	included.

	To better understand fee escalation and the recently introducted load and open ledger
