Subject: reduce some ridiculously large spin counts
X-Git-Url: http://nsz.repo.hu/git/?p=musl;a=commitdiff_plain;h=77f15d108ee021d4dfbeebe793661131c4470d4d

reduce some ridiculously large spin counts

these should be tweaked according to testing. offhand i know 1000 is
too low and 5000 is likely to be sufficiently high. consider trying to
add futexes to file locking, too...
