I wait for these results. From what you show it seems that the garbage
collector is indeed not the major problem, but I am definitely puzzled
about the memset/strncmp calls, which are almost nowhere used in ECL (in
particular "strncmp"!). As for the *sigprocmask*, they can be probably
removed by a careful replacement of setjmp/longjmp with the versions
that do not save signals (_setjmp/_longjmp in some platforms).
