Mutexes may be recursive in the sense that a thread can lock a mutex which it
had already locked before (instead of dead locking the entire process in this
situation by starting to wait on a mutex which will never be released while the
-thread is waiting) but using them is not recommended and they are {\bf not}
-recursive by default. The reason for this is that recursive mutexes are not
-supported by all Unix flavours and, worse, they cannot be used with
-\helpref{wxCondition}{wxcondition}.

For example, when several threads use the data stored in the linked list,
modifications to the list should only be allowed to one thread at a time
