Arguments: (lock &key timeout norecursive seized whostate) &body body
This macro executes the body with lock
seized. Unlike process-lock,
with-process-lock protects
against a single process trying to seize a lock it already owns. If
executed dynamically inside another with-process-lock for the same lock, and if
norecursive is nil,
with-process-lock is a no-op. If
norecursive is t, an error is signaled. The
default value of norecursive is nil.
See also process-unlock, process-lock-locker, and make-process-lock.
