sharable-lock-interrupted-error

This error is signaled if a function called via process-interrupt attempts to obtain a lock while the process is in the middle of obtaining an exclusive lock. In that state, the process must allow interruptions but cannot allow any access to the lock from the same process. The only action possible is for the process-interrupt function to propagate the error to the caller of process-interrupt, where a second attempt may succeed.
