Yes. It slowed down builds, and it often triggered bizarre build
failures which were NOT bugs in the program, but in the toolchain or in
some core library like glibc, which in turn delayed important updates to
the affected packages.
I.e., it was discovering bugs ... not in your program but in glibc, gcc,
etc. (I have experienced this couple of times with pspp on Sparc).
