locking questions:

example 1:

:0w :message.lock
* some test(s)
{
:0c
message

:0
| process-message
}

Question 1:

Will the above script leave the lock file in place, untill after the
process-message program exits?
Will the program be able to write to the message file.

Example 2:

:0 :test.lock
{
some scripts
}

Question 2:

Will the lock file "test.lock" be inplace for the duration of the above
set of scripts?
Will the scripts within be able to write to the test file?
