Further to https://github.com/llvm/llvm-project/pull/147134#discussion_r2337246489, switch to use the madvise() api to page in mmap'd files and 1) All new code compiled in #if LLVM_ENABLE_THREADS is set so it can be seen where the changes were from this PR. 2) The new PR moves to use madvise() instead of the ad-hoc page referencing code I wrote which should avoid SIGSEGVs if the buffer is deallocated. 3) A new property SerialBackgroundQueue().stopAllWork to be used to stop background workers when there is no further call for them. Usually the background "page-in" threads have completed first but it seems with this troublesome test this is not always the case and buffers stored in the static input file cache are being deallocated while being referenced. --------- Co-authored-by: James Henderson <James.Henderson@sony.com>
