Comment (by neverpanic):

 Trace mode should only use one file descriptor per thread in addition to
 what is being used without trace mode.
 I doubt that CMake's linking tests would usually use 1024 file
 descriptors, so that means there's probably a leak somewhere, possibly
 related to dynamically creating and destroying threads.

 I'm in favor of sending this patch upstream, since from what I understand
 this will also lead to memory corruption if a CMake build ever tried to
 legitimately open more than 1024 files, right?

 Thanks for the extensive debugging. I had seen those error messages before
 and traced them to the invocation of select(), but couldn't figure out
 what was wrong.
