Abstract
The systems and methods described herein are directed at controlling access to a data structure. A data field is included within the data structure. The data field includes information about the accessibility of the data structure. In response to an attempt to access the data structure by a first thread, the data field is configured to identify that the data structure is not accessible by another thread. The first thread can then access the data structure. In response to an attempt to access the data structure by a second thread, the second thread is configured to determine from the data field that the data structure is being accessed by the first thread.
