# When debugging with "target remote |", the inferior's output is
|
|
# connected to a pipe, and if GDB doesn't flush the pipe while the
|
|
# inferior is running and the pipe becomes full, then the inferior
|
|
# deadlocks:
|
|
#
|
|
# 1. User sets breakpoint, and types "continue"
|
|
#
|
|
# 2. Inferior prints to stdout/stderr before reaching breakpoint
|
|
# location.
|
|
#
|
|
# 3. The output pipe becomes full, so the inferior blocks forever in
|
|
# the printf/write call.
|
|
#
|
|
# 4. The breakpoint is never reached.
