| | | | | | | | | | | | | | | | to do what they are supposed to: under some circumstances output data would be truncated, or the buffer would not actually be flushed (possibly leading to overflows when the caller assumes the operation succeeded). Change the semantics so that these functions ensure they complete the operation before returning. Comment out diagnostic code enabled by '-D reports' which causes an infinite recursion and an eventual crash. Patch developed with assistance from ru and assar. Notes: svn path=/head/; revision=80224
