Modifying a series of lock acquire and release operations to use a single lock reservation

A system for managing a lock to a resource, comprising:

• a processor;
• and
• a computer readable storage medium having computer readable program code embodied therein that when executed by the processor performs operations, the operations comprising
• scanning a representation of source code to determine a series of acquire lock program statement and release lock program statement pairs to acquire and release a lock by a thread;
• modifying a first acquire lock program statement in the series of acquire lock program statements to be an acquire with reserve program statement that when executed by the thread causes the thread to acquire the lock and indicate the lock as reserved for use by the thread;
• and
• modifying a last release lock program statement in the series of release lock program statements to be a release with cancel program statement that when executed by the thread causes the thread to release the lock and indicate the lock as not reserved.
