Subject: [android] pthread_kill cannot be used safely on android
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=e0798bd9229268714008cf05b750053faf39288e;p=gc

[android] pthread_kill cannot be used safely on android

Android's fork() function does not properly update the
pthread_internal_t->threadid variable to point to the tid of the
fork()'d thread, and instead still points to the pid of zygote.
As a result we need to track the android tid's manually since
gettid() is sane, and use an alternate to pthread_kill on android
Additionally, disable sgen support on android until the same
work has been done there
