Documentation of {{{BMessage::Previous}}} says that caller SHOULD delete
resulting BMessage. But when i do that, BLooper crashes soon after return
from {{{MessageReceived}}}.
Documentation:
https://www.haiku-
os.org/docs/api/classBMessage.html#a57c84d02e54ef19fd1516d9bf7e3fe45
I'm attaching mini application that shows the problem. I know it's strange
to send message to itself, but it's to closely mimick code that discovered
the problem.
My Deskbar replicant has to use {{{PostMessage}}} because on Haiku it
cannot get Deskbar location otherwise (outside of some ugly hacks):
https://github.com/haiku/haiku/blob/4824497d01271c34dc86e092f2df96d6352e452c/src/kits/interface/Deskbar.cpp#L121-L124
So it posts message and waits for reply in {{{MessageReceived}}}, where it
gets previous message to make sure it's the right reply message.
