Comment (by erikd):

 > ghc does normally clean up its temporary directory.

 On my machines its leaving behind two kins of things:

 * An normally empty /tmp/ghcNNN_M directory where NNN looks like a process
 id and M looks like it may be a thread number (0 is most common, followed
 by 1, 2, 3 etc). When these directories are not empty, they contain things
 like ghc_ZZ.s, ghc_ZZ.o etc.

 * A /tmp/ccXXXXXX file which contain what looks like command line options
 for GCC, one per line. This is probably a result of commit 296bc70b5ff6c.
