# Note [residency]
#
# Residency (peak_megabytes_allocated and max_bytes_used) is sensitive
# to when the major GC runs, which makes it inherently inaccurate.
# Sometime an innocuous change somewhere can shift things around such
# that the samples occur at a different time, and the residency
# appears to change (up or down) when the underlying profile hasn't
# really changed.
#
# However, please don't just ignore changes in residency.  If you see
# a change in one of these figures, please check whether it is real or
# not as follows:
#
#  * Run the test with old and new compilers, adding +RTS -h -i0.01
#    (you don't need to compile anything for profiling or enable profiling
#    libraries to get a heap profile).
#  * view the heap profiles, read off the maximum residency.  If it has
#    really changed, then you know there's an issue.
