+Pan-STARRS does not have a strong requirement for multithreading capability.
+The memory management functions, defined below, must be written to be
+thread-safe.  The use of \code{static} variables should be keep to an absolute

+synchronization for PSLib's fundamental datatypes (\code{psArray},
+\code{psVector}, etc.) is left as an exercise for the end-user.
