Title:
  pread/pwrite does not used in sqlite3 (USE_PREAD not defined)

Status in “sqlite3” package in Ubuntu:
  New

Bug description:
  Binary package hint: sqlite3

  sqlite 3 in maverick for 80x86 does not compiled with USE_PREAD or
  USE_PREAD64. So during strace, we can see llseek(), write() syscalls.
  it's not optimal on current kernel. performance may be higher.

  It will be nice, if this package in 10.10 and 11.04 will be compiled
  with -DUSE_PREAD64. It will reduce syscalls extra time waste.
