Oh, I forgot, and the condition variables:

make-condition-variable
condition-variable-signal condvar
condition-variable-broadcast condvar
condition-variable-wait condvar
condition-variable-timedwait condvar seconds

There doesn't seem to be an option to use a recursive condition
variable internal lock, but this API sits on top of the pthread one and
generally a mutex/lock is used in combination with them, which could be
recursive.  It seems that condition variables are not currently
available on Windows.
