73fd87baf5 Don't attempt to wake tasks that aren't blocked.
It's possible for a supervised task to kill and wake its supervising
task then immediately try to wake it again if the supervising task
has joined the supervised. This is the easiest way to prevent that.

3b3cd550d4 Cast NULL to uintptr_t when calling rust_task::start().
On gcc 4.5.1 (fedora 14 i686) rust_test_runtime.cpp fails to compile
with the following error:

  rt/test/rust_test_runtime.cpp:57:61: error: passing NULL to non-pointer argument 3 of ‘void rust_task::start(uintptr_t, uintptr_t, uintptr_t, size_t)’

The explicit cast works around the error.

97d6342bf0 Synthesize a flush_chan upcall right before a channel's ref_count drops to zero. This should only happen in the Rust code and not in the drop glue, or on the unwind path. This change allows the task owning the channel to block on a flush and delete its own channel. This change also cleans up some code around rust_port and rust_chan. 2010-08-09 08:15:34 -07:00
