msgstr ""

msgid ""
"In essence, a Condition object combines the functionality of an :class:"

"Condition re-acquires its lock and this method returns ``True``."
msgstr ""

msgid ""
"Note that a task *may* return from this call spuriously, which is why the "

msgid "A Semaphore object.  Not thread-safe."

msgid ""
"A semaphore manages an internal counter which is decremented by each :meth:"

msgid "A barrier object.  Not thread-safe."

msgid ""
"A barrier is a simple synchronization primitive that allows to block until "
