The test requires tons of memory and results various failures, mainly

exhaustion when the node under test doesn't have much resources.
This change makes use of -tcpbig flag to enable the test.

This change is an experimental implementation of asynchronous
cancelable I/O operations on Plan 9, which are required to
implement deadlines.
There are no asynchronous syscalls on Plan 9. I/O operations
are performed with blocking pread and pwrite syscalls.
Implementing deadlines in Go requires a way to interrupt
I/O operations.
It is possible to interrupt reads and writes on a TCP connection
by forcing the closure of the TCP connection. This approach
has been used successfully in CL 31390.
However, we can't implement deadlines with this method, since
we require to be able to reuse the connection after the timeout.
On Plan 9, I/O operations are interrupted when the process
receives a note. We can rely on this behavior to implement
a more generic approach.
When doing an I/O operation (read or write), we start the I/O in
its own process, then wait for the result asynchronously. The
process is able to handle the "hangup" note. When receiving the
"hangup" note, the currently running I/O operation is canceled
and the process returns.
This way, deadlines can be implemented by sending an "hangup"
note to the process running the blocking I/O operation, after
the expiration of a timer.
Fixes#11932.
Fixes#17498.

When a Go program crashes with GOTRACEBACK=crash, the OS creates a
core dump. Include the text-formatted output of some of the cause of
that crash in the core dump.
Output printed by the runtime before crashing is maintained in a
circular buffer to allow access to messages that may be printed
immediately before calling runtime.throw.
The stack traces printed by the runtime as it crashes are not stored.
The information required to recreate them should be included in the
core file.
Updates #16893
There are no tests covering the generation of core dumps; this change

This adds (reentrant) locking to runtime.gwrite, which may have an
