Thanks. Some questions about the proposed patch:
- What defines HAVE_MMAP?
  I don't believe we currently have a configure check for it, should we?
- The guard checks for HAVE_MMAP, but the code calls mremap.
  Should we have a HAVE_MREMAP guard and configure check instead?
- On which systems did you test and what were the make check results?
